I don't know if this is worth it, but in the Perl world this is a
fairly common idiom:
my $home = $ENV{HOME} || (getpwuid($<))[7];
Sometimes you're executing under some buggy wrapper that's scrubbing
your environment. I recall running into this issue e.g. on some odd
Solaris webserver, which was executing CGI scripts under my user, but
$HOME wasn't set.
