Re^3: How to sovle this, if i use strict i'm getting error.

[jhourcle]

They think it's a bad idea because 'use strict' complains ... but if you know that what you're trying to do is correct, you can shut off 'use strict' for the specific complaint that it has:

use strict;
use warnings;

for my $i ( 1 .. 2 ) {
  $a = 'test'.$i;
  no strict 'refs';
  &$a;
}

sub test1 { print 'test1'; }
sub test2 { print 'test2'; }

So where's the problem with that? None, really. I mean, it doesn't propogate, so you're still protected in the subroutine you're calling:

use strict;
use warnings;

for my $a qw( test1 test2 ) {
  no strict 'refs';
  &$a;
}

sub test1 { print 'test1'; }
sub test2 { my $x='test3'; &$x }

PS. For the original poster -- it's convention that you don't use $a and $b as variable names, unless you're dealing with sorting.

You don't actually need to change the current strictures:

use strict;
sub foo {
        print "Foo";
}

sub bar {
        print "bar";
}

main->can("foo")->();
