Hmm.... I couldn't coax it to do that on my Linux box. It appears env expects the shell to have split up the arguments before they're handed to it, so when execve hands it one long string of file and arguments, it thinks the blanks are part of the file name. That's judging from the error message I get: env: perl -w: No such file or directoryThat's not such a big deal with -w since you can substitute use warnings, but is a problem with -T, which has to appear early on. There may be some clever way to do with the env trick. I think I'll just stick to regular ol' shebangs....
