Y'all are quick on the send button. To repeat...
I thought this is possible, but maybe I'm wrong. Ok, here's the issue:
I want to print the values of a bunch of variables so I thought I'll take a shortcut and do this:
foreach (qw(var1 var2 var3 var4)) { print "$_ -> ${$_}\n"; }
I had thought that interpolating the variable name ("${$_}") would cause
Perl to interpret the correct variable name & print its value, but it
printed nothing.
Is my syntax wrong or is this not possible at all? I checked Mr. Camel, but did not find anything there on this specifically.
Thanks,

Are the variables lexical?
"Only package variables are accessible through symbolic references, because symbolic references always go through the package symbol table." (Camel, 3rd Edition, p. 264)
$global = "GLOBAL"; my $lexical = "LEXICAL";
for (qw(global lexical)) {
print $$_, "\n";
}This prints: GLOBAL
