Hi all,

I have a string defined as follows: 
my $str = 'params.$idx.arg';

[download]
$idx will be assigned with integer values in a loop as follows: 
for my $idx (0..10) {
    &do_something($str);
}

[download]
The thing is that I want $str in the loop to be interpulated with the value of $idx in each loop iteration (the above code will not take there of course), meaning do_something() will get a different parameter each loop iteration ('params.0.arg', 'params.1.arg', etc.).
How can I achive that?

Thanks
