[m-users.] "operator precedence error" - Mercury bug?

[Volker Wysk]

Hi

This simple module won't compile:

:- module test1.
:- interface.
:- import_module char.
:- pred f(char::in) is semidet.

:- implementation.

f(A) :-
    A = '/'.


I get this error message:


make -k test1
mmc -E --make --output-compile-error-lines=200 "test1" --ml posix
** Error making `Mercury/int3s/test1.int3'.
test1.m:009: Syntax error at token '/': operator precedence error.
Makefile:2: recipe for target 'test1' failed
make: *** [test1] Error 1


The error does NOT occur when you substitute the '/' for something
different, for instance 'x'. To me this looks like a Mercury bug. 

Bye
