117// The append built-in function appends elements to the end of a slice. If

171// The make built-in function allocates and initializes an object of type
172// slice, map, or chan (only). Like new, the first argument is a type, not a
173// value. Unlike new, make's return type is the same as the type of its
174// argument, not a pointer to it. The specification of the result depends on
175// the type:
176//
177// Slice: The size specifies the length. The capacity of the slice is
178// equal to its length. A second integer argument may be provided to
179// specify a different capacity; it must be no smaller than the
180// length. For example, make([]int, 0, 10) allocates an underlying array
181// of size 10 and returns a slice of length 0 and capacity 10 that is
182// backed by this underlying array.
183// Map: An empty map is allocated with enough space to hold the
184// specified number of elements. The size may be omitted, in which case
185// a small starting size is allocated.
186// Channel: The channel's buffer is initialized with the specified
187// buffer capacity. If zero, or the size is omitted, the channel is
188// unbuffered.

212// The close built-in function closes a channel, which must be either
213// bidirectional or send-only. It should be executed only by the sender,
214// never the receiver, and has the effect of shutting down the channel after
215// the last sent value is received. After the last value has been received
216// from a closed channel c, any receive from c will succeed without
217// blocking, returning the zero value for the channel element. The form
218//

224// The panic built-in function stops normal execution of the current
225// goroutine. When a function F calls panic, normal execution of F stops
226// immediately. Any functions whose execution was deferred by F are run in
227// the usual way, and then F returns to its caller. To the caller G, the
228// invocation of F then behaves like a call to panic, terminating G's
229// execution and running any deferred functions. This continues until all
230// functions in the executing goroutine have stopped, in reverse order. At
231// that point, the program is terminated with a non-zero exit code. This
232// termination sequence is called panicking and can be controlled by the
233// built-in function recover.
234func panic(v any)
235
236// The recover built-in function allows a program to manage behavior of a
237// panicking goroutine. Executing a call to recover inside a deferred
238// function (but not any function called by it) stops the panicking sequence
239// by restoring normal execution and retrieves the error value passed to the
240// call of panic. If recover is called outside the deferred function it will
241// not stop a panicking sequence. In this case, or when the goroutine is not
242// panicking, or if the argument supplied to panic was nil, recover returns
243// nil. Thus the return value from recover reports whether the goroutine is
244// panicking.

247// The print built-in function formats its arguments in an
