Unlike argv[0] in C, $0 in Perl is not spoofable. See FindBin is broken (RE: How do I get the full path to the script executing?) for more details.
But $0 is certainly inappropriate for getting the full path to "the current working directory" or "where the script was called from" (though I could see misinterpretting this last phrase to mean the full path to the script). $0 often tells you the full path to where the script resides.
