Similar to `Array#empty?`

def find(&) : ASTNode | NilLiteral #

Similar to `Enumerable#find`

def first : ASTNode | NilLiteral #

def map_with_index(&) : ArrayLiteral #

Similar to `Enumerable#map_with_index`

def of : ASTNode | Nop #

Returns the type specified at the end of the array literal, if any.

This refers to the part after brackets in `[] of String`.

def push(value : ASTNode) : ArrayLiteral #

Similar to `Array#push`.

def reduce(memo : ASTNode, &) : ASTNode #

Similar to `Enumerable#reduce`

def reduce(&) : ASTNode #
