while this code compiles fine

this one does not

else:
raise newException(ValueError, "could not convert string '$#'

while this also compiles
from strutils import `%`
type
Roles = enum
user,catering,manager,sysadmin
converter toRole(s : string): Roles =
case s
of "user":
Roles.user
of "catering":
Roles.catering

else:
Roles.sysadmin
Isn't it bad to force to write the return explicitly only because one branch of
the case does not return?
