Can we load perl module without ".pm" file extension or some other file extension?

Can we load perl module without ".pm" file extension?

Can we have perl module with some other file extension such as "dll", "so" or "lib"

Just curious to know, how only "pm" files can be loaded as package/module in perl.

You can load any file you want with require "file_name";, with or without extension. The only requirement is that the file is syntactically valid Perl and that it returns a true value in order to indicate that loading the module was successful;

The usual use Module; is basically only a shortcut for

BEGIN {
  require Module;
  Module->import();
}

and require Module; (note the missing "..." around the module name!) looks for "Module.pm" in all the directories listed in @INC.

So: require with a string loads any file, require with a Bareword looks for "Bareword.pm" in @INC.
