patch 8.2.0044: expression type is used inconsistently Commit: https://github.com/vim/vim/commit/07a3db89b8953bd0964895badb3b662f7514bc10 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Dec 25 18:14:14 2019 +0100 patch 8.2.0044: expression type is used inconsistently Problem: Expression type is used inconsistently. Solution: Add "ETYPE_IS" and "ETYPE_ISNOT" as separate enum values. Rename "TYPE_" to "ETYPE_" to avoid confusion.

function Test_Comparators()
  try
    let oldisident=&isident
    set isident+=#
    call assert_equal(1, 1 is#1)
  finally
    let &isident=oldisident
  endtry
