Running this code with -w, use strict or use diagnostics doesn't reveal anything useful, except that when the variables are lexically scoped with my that the shell escapes seem to have different precedence, being interpreted as an array (which doesn't exist) instead of a scalar. Does anyone have any ideas why? 
#!/usr/bin/perl

$a = 'name';
$b = 5;

my $c = 'name';
my $d = 5;

print "${a}[$b]" eq "${c}[$d]" ? "ok\n" : "booger\n";
