I think this will work for me. I'm building the tactic to unify two arguments using Unicoq.

Written from mobile. Excuse my limited communication.

Hi Beta,

You should rather use uconstr and explicitely program which one is interpreted first and pass the sigmas around, merging is bad style. Maybe a hint about your example could help us.

This does not contradict what I said, quite the contrary. Each of your
evarmaps is an extension of the evarmap from the goal, but they are
incomparable between each other. Thus, a good generator of evar leaks.

You should try to merge them...

Sorry, meaning? I don't see anything like a merge for evars in evd.mli. Should I define my own?
