Oh, it's much more horrible than that. RFC822 contains this example:

  Muhammed.(I am  the greatest) Ali @(the)Vegas.WBA

which parses to:

  Muhammed.Ali@Vegas.WBA

Perl's Mail::Address does decipher that correctly.

TBH, so do I. That's all done by Mail::Address's format() method. We
could probably convince it to be less magical, but perhaps it's best to
just leave it alone. Presumably that logic has some historical basis,
and as you note, it's a mistake to be passing these fields into
send-email in the first place.
