As I don't ever use perldoc, I was just looking for the minimal easy fix
and throwing in a case statement to run gzcat/bzcat/cat on a file seemed
easier than anything which would involve rewriting the parsing.

And it seemed to make sense that parsing troff source is easier than
the formatted output so I didn't think much about it. However, I just
looked at the perldoc man page and it seems that I can get POD source
by using perldoc -u (so _perldoc is clearly very minimal). That's nice
and easy to parse and yields this, much shorter function:

#autoload

local expl

: ${(A)_perl_builtin_funcs:=${(u)${${(M)${(f)"$(_call_program functions \
    perldoc -u perlfunc)"}:#\=item [a-z]*}#* }%%[^a-z]*}}

_wanted functions expl 'perl built-in function' compadd "$@" -a - \
    _perl_builtin_funcs
