2.3.16 Byte-Code Function Type

The byte compiler produces byte-code function objects. Internally, a byte-code function object is much like a vector; however, the evaluator handles this data type specially when it appears as a function to be called. See section 16. Byte Compilation, for information about the byte compiler.

The printed representation and read syntax for a byte-code function object is like that for a vector, with an additional `#' before the opening `['.
