As I' ve read in "Programming Perl", double-quoted strings are subject to
variable interpolation of scalars and list values. Nothing else
interpolates.
So the following perl code won't compile:
$st = "!--- &get_header("Users")---!";
sub get_header{
$hnd->fixHead(@_);
}
also the following line of code won't compile (which does the same as the
above):
$st = "!--- $hnd->fixHead("Users")---!";
If I use the '.' operator (concatenation) my work is done. For example:
$st = "!--- " . $hnd->fixHead("Users") . "---!";
My question is if there is any way, that will let me do such an
interpolation, without concatenation. For example I've started reading
about overloading the stringify, but I realized that it isn't what I'm
looking for.
Is there a way to have the return value of $hnd->fixHead("Users")
interpolated into my string, without concatenation?
Thank you,
Giannis
