Re^8: Line numbers

Because parens around sub-args are optional.

print '', (caller(0))[0]; means print ( '', (caller(0))[0] );

But providing explicit parens after a sub-name will disable automatic grouping of args.

Ahhh, I think I understand. That is why this does work, right?

print ((caller(0))[0]);
