in thread conditional match in regex

The problem seems to be stated: either $val or <val>:
$ perl -le'$_=pop;/([\$@*%]|(<))(.*)(?(2)>)/;print"($1)($3)"' '$xyz'
($)(xyz)
$ perl -le'$_=pop;/([\$@*%]|(<))(.*)(?(2)>)/;print"($1)($3)"' '$xyz>'
($)(xyz>)
$ perl -le'$_=pop;/([\$@*%]|(<))(.*)(?(2)>)/;print"($1)($3)"' '<xyz>'
(<)(xyz)

    '$xyz>' is definately NOT a valid symbol table entry.

      Right.  I was just showing how the regex works.
      $ perl -le'"%xyz"=~/([\$@*%]|(<))(.*)((?(2)>))/;print"($1)($3)($4)"'
(%)(xyz)()
$ perl -le'"%xyz>"=~/([\$@*%]|(<))(.*)((?(2)>))/;print"($1)($3)($4)"'
(%)(xyz>)()
$ perl -le'"<xyz>"=~/([\$@*%]|(<))(.*)((?(2)>))/;print"($1)($3)($4)"'
(<)(xyz)(>)
