The tactic with the closest behavior is the (introduced in 8.5) "unshelve" tactical. Given a goal such as:


Goal P.

tac1.

Grab Existential Variables.

all:tac2.


where tac1 generated the unsolved existentials, one can (usually) replace this by:


Goal P

(unshelve tac1); tac2.


However, there are some known bugs that prevent this from always working, for instance: https://coq.inria.fr/bugs/show_bug.cgi?id=4509

Hi all,

I was wondering if there is a tactic which simply does the job of "Grab Existential Variables" vernac?

Thanks!
