I *like* it!

A fellow Monk and I recently wrote a tool like this ourselves, but the in-memory eval() isn't a capability of our implementation. Anyway, I have a slight improvement to offer on your script. It concerns the mundane issue of where to save a file on disk. Your default /tmp would be fine on a single-user workstation but I thought about a multi-user system where security / privacy might be a greater concern, and one would want to confine one's activities to one's ~USER/ ($HOME) dir.

This small patch makes sure that such a directory exists before allowing the script to continue if writing to disk is going to be needed.

Here's the germane portion of what this change entails:

use File::Glob qw(:glob);
use File::Spec qw(file_name_is_absolute catfile);

# Configure this to an existing dir in your $HOME:
my $home_space = '';
# /end  user config.

my  ($HOME, $directory);

if ($opt_m or $opt_M or $opt_f or $opt_F) {

        my $filename = $opt_f || $opt_F;
    die "Don't pass an absolute path!\n" if
        ($filename and File::Spec->file_name_is_absolute($filename));

    $HOME = (bsd_glob('~'.$ENV{LOGNAME} , GLOB_TILDE | GLOB_MARK))[0];
    $HOME = ($HOME =~s%/\Z%%) ? $HOME : '';

    # Be kind to some Win32 users, comment this out:
#    die "No HOME found, no place to stash the code!\n" if not $HOME;

    # Directory to save fetched code in:
    $directory = $home_space ?
        File::Spec->catfile($HOME, $home_space) : $HOME;
    die  "$directory does not exists.\n" if not -e $directory;
}

Fun.
