I'm not familiar with File::Glob but perl does have a built in glob which I have used it in the past.

Also I just looked at the docs for File::Glob and it looks like bsd_glob allows for flags which the built in glob does not. However the perldoc for glob notes this:

Beginning with v5.6.0, this operator is implemented using the standard "File::Glob" extension. See File::Glob for details.

In fact on my system (Perl v5.8.0, Slackware 9.1) glob matches the tilde in my username:

[frink@truth]$perl -e 'print map $_ .= "\n" , glob("~frink/tmp/*");'
