__LINE__ and __FILE__When printing traces it is often useful to include a description of the location of the trace. The poke compiler provides two builtins for this purpose.
__LINE__Expands to an unsigned 64-bit integer containing the current line of the program being compiled.
__FILE__Expands to a string with the name of the file currently being compiled. If the
program is read from the standard input (like in the REPL) then this
is "<stdin>".
