if File::Find is improved to support patterns, ... But why the Perl community didn't do it? Reason is simple, because of the existance of File::Glob, there is no point to repeat/reinvent the same functionality in another class

Nope. File::Find doesnt have any filtering mechansim explicitly built into it for a very good reason that has nothing to do with File::glob. Basically the callback mechanism used by File::Find is about a million times more powerful than any filtering technique they could have provided. If you want to do pattern matching on the names then just do it in the wanted function:

#perl -l
use File::Find;
find sub{print $_ if -f and /\.txt$/i},@INC;
[download]

will print out all text files in a directory reachable from the paths in @INC for example.

And if this really is not sufficient (id be suprised) then take a look at File::Find::Rules
