   You can remove textinsert from let and make it a defvar instead.

     (defvar textinsert nil)

Yes, but that would defeat the presumed intention of using `textinsert'
as a local variable.  Practically, this means `set-local-key-insert'
invocations clobber previous invocations' state (last invocation wins).

Probably OP wants `lexical-let'.
