well, it was mostly a straight copy-n-paste. just defined a bunch of functions following pin_alias and param_alias and creating signal_alias for a new 'sig' type, as andy stated earlier. i partly rewritten my configs using 'alias sig' . can't say that i'm completely satisfied how they look now, but i need to experiment a bit to think it thru.... but here it is. if someone think it is worth refining - please, comment
