Hi
 
I have a doubt whether it is possible to evaluate a pattern before using it in the pattern matching. 
 
For eg
 
string =~  /$pattern/
 
here $pattern is a pattern string contains some perl commands like lenght(str) etc. I want these commands to be evaluated, and the result of this evaluation has to be used in the actual pattern matching.
 
Thanks in advance
 
Regards
Kumar
