mercury/tests/invalid/multimode_syntax.err_exp
Zoltan Somogyi 2bf3432804 Better diagnostics for bad use of language constructs. 
compiler/typecheck_error_undef.m:
    Stop generatic diagnostics that a language construct "should be used
    as a goal, not as an expression", because exactly none of those
    constructs are complete goals by themselves.

    Instead, generate messages that specify that those constructs
    should be

    - "part of a goal", for e.g. equal signs,
    - "a prefix before a goal", for e.g. "impure", or
    - "a connective between goals", for e.g. ";"".

    Also, address a review comment.
