Not to take away from any of the great feedback you supplied to the OP,
or to be ignorant or argumentative in any way, but I recently found it
handy to use something similar to this ( personally ) unrecommended and
noisy piece of syntax to extract the result of a function within quotes:
#!/usr/bin/perl
use warnings;
use strict;
my $string = "d'oh";
my $return_from_sub_in_quotes = "${\( marine( $string ) )}";
print "$return_from_sub_in_quotes\n";
sub marine { return shift; }
__END__
> $scalar_sig = printFile( $signature );
...of course, John's method above is a far better approach, and is the
right way. On my next pass through the particular routine that uses the
above noise, I'll be replacing it with something more maintainable :)
