Is hungarian notation applicable to perl ?
In perl, reference to anything is a simple scalar, and has the '$' sigil. It's sometimes hard to say what kind of reference it is. 
I personally prefix variable names for references with a letter, which indicates ref type. Examples:    

    my $aValues; # reference to array
    my $hValue;  # reference to hash
    my $oValue;  # object
    ...

Some coders seem to be almost allergic to this notation. Do you use such notation ? Does it have any disadvantages ?
