in thread capturing program output

You are right, but I think it's really a matter of style...

won't open $file,"myprogram here |" or die ... work as well, placing the filehandle reference in $file?

Thanks for catching the lack of error-checking...

    Only in perl 5.6, in which it's a new feature. 5.5 didn't do that. (Unless you pre-populated the variable with a IO::Handle-ish object.) And it has to be a variable that only has undef in it. Otherwise, it's treated as a symbolic reference, which may not succeed if you have "use strict refs" turned on.
