If you want the exact same function as the backticks, why not just
make a small subroutine?
Maybe because it's unnecessary, since there already is an operator
equivalent to backticks?
$exec = "ls -l";
$src = syscall($exec);
sub syscall{
return `$_[0]`;
}
should work.
Should it? Did you try it? syscall() is a built-in Perl function, so
the above does *not* work.
