Description

class EnumDictBug
	def main is shared
		keymap = { 
			ConsoleKey.Numpad0: 'kp0',  # typo
			#ConsoleKey.NumPad0: 'kp0',  # this is correct enum
			ConsoleKey.NumPad1: 'kp1'
		}
		assert keymap.count == 2

cause compiler exception and barf with

Change History

Changed 8 years ago by Chuck

  • owner set to Chuck
  • status changed from new to assigned
  • summary changed from Unresolvable Enum value in Dict literal causes compiler crash to Unresolvable expression in dict literal in assignment causes compiler exception

Enums aren't part of the source problem. Something as simple as this will trigger it:

d = {badname: 1}

Changed 8 years ago by Chuck

  • status changed from assigned to closed
  • resolution set to fixed

Fixed in changeset:2399

Thanks for the report.
