Topic: or.elim unknown identifier
Bernd Losert (Dec 04 2021 at 19:30):
I have this piece of code:
  le_conv := begin
    intros y l₁' l₂' h₀ h₁,
    or.elim h₁ _ _
  end,
For some reason, the first error that I get from this is error: unknown identifier 'h₁'. I don't understand why though since  h₁ is right there. Help!

or.elim isn't a tactic but a term. Try refine or.elim h₁ _ _ instead.

Works. Good to know. Thanks.
