There is minimal test and description. Below is how I run tests. See -- one is half a seconds, and other is 20 seconds. 


# ./show_me_the_problem.sh 


****************************
here are the two programs:
-rwxr-xr-x 1 root root 177 wrz 30 17:57 run_fast.pl
-rwxr-xr-x 1 root root 190 wrz 30 17:57 run_slow.pl


****************************
the difference is: 
10c10,11
< my $lst = list_extr(\( "(" . $inp . ")" )); 
---
> my $par = "(" . $inp . ")"; 
> my $lst = list_extr(\$par); 


****************************
data is the same... let's run them...
time ./run_fast.pl | wc -l
9506

real    0m0.476s
user    0m0.456s
sys    0m0.016s


****************************
time ./run_slow.pl | wc -l
9506

real    0m22.591s
user    0m22.556s
sys    0m0.012s


****************************
seee... programs are almost the same... but their time is totally dife
