Subject: Modula-3 compiler bug?

From: Sharon E. Perl <sharon@proton.LCS.MIT.EDU>

Bill & Eric,

Maybe you've heard about this one already. In the following program,
*************************************************************************)

    MODULE Main;
    TYPE Rec = RECORD a: INTEGER END;
    VAR  r := Rec;
    BEGIN
      INC(r.a)
    END Main.

(*************************************************************************
I get the error message:

    "bug.m3", line 5: unknown qualification '.' (a)"

rather than a complaint about the variable initialization for r.  The error
message had me mystified for a while until I noticed my typo. Seems like the
compiler should catch the error when it tries to assign the type Rec to a
variable.
