Okay Adam... use strict is in place. Here is another example of the problem:
use strict;
my $evaled = 0;
# very simplified...
sub makesub {
my($name) = @_;
return "sub $name { print \"\$var \"; }";
}
sub a {
my($var) = @_;
if(!$evaled) {
eval(makesub("somesub"));
$evaled=1;
}
}
a("what");
somesub();
a("the");
somesub();
prints:
what what
I'd like it to print "what the". Basically I don't
want to have to eval every single time, it could be
in the millions... but I'd still like access to the
my variables of the sub that it was first created
in. I don't even mind if I have to call the sub from
the one that encloses it. i.e:
sub a {
my($var) = @_;
if(!$evaled) {
eval(makesub("somesub"));
$evaled=1;
}
somesub(); # only place I call it from.
# only want to eval once per
# program execution, but have
# access to the my variables for
# each calling of "a"
}
Perhaps it's impossible.
