Hmm, I don't know if it's feasible to do in Perl, but maybe check
whether the function wants to return something in list context and throw
an appropiate error message?
In perl, if there is any ambiguity it is the called function that is
responsible for checking, not the caller. See "perldoc -f wantarray".
PLPerl explicitly passed G_SCALAR as a flag on all calls to plperl
routines. So returning a list is a case of pilot error.
