[mercury-users] $pred doesn't work in lambda expressions

[Nicholas Nethercote]

Hi,

I tried using $pred in a lambda expression and got this:

   Uncaught Mercury exception:
   Software Error: hlds_code_util.m: Unexpected: cons_id_to_tag: implementation_defined_const

It's easy to work around, but I thought it might be worth mentioning.
