Comment(by dports@…):

 I think what we actually want is

 {{{
     if {[string match py-* [option name]] &&
         [string match py\[0-9\]\[0-9\]-* [option subport]]} {
         return [string range [option subport] 2 3]
     } else {
         return [option python.default_version]
     }
 }}}

 which should do the right thing for py-foo stub ports, pyXX-foo subports,
 and apps (not name py-foo)
