Built-in functions

FZLang provides built-in functions that are available in every program.

Exit: exit

fn exit(uint code)

Takes an unsigned integer argument and exits the program with the specified code.

Print to stdout: printline

fn printline(value)

Accepts any value and writes it to standard output. Primitive values are printed directly according to their types. Objects are printed as obj<...>, where ... is a list of their field values. Each field is printed with its type and value in the format T<V>, where T is the type name and V is the current value.
