#1383: mistaken qualified infix syntax could have a nicer error message
------------------------------+---------------------------------------------
Reporter: Isaac Dupree | Owner:
Type: feature request | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.6.1
Severity: minor | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: | Architecture: Unknown
------------------------------+---------------------------------------------
Consider the expression {{{ Prelude.(+) }}};
we get {{{Not in scope: data constructor `Prelude'}}}.
Unfortunately this is valid code if the module-referencing name also is
the name of an in-scope data constructor. In the common case that it
isn't, at least (a cursory inspection doesn't find any such exports in the
libraries, e.g. Data.Map doesn't export a data-constructor Map), a message
to the effect that infix operators must be qualified like (Prelude.+)
instead, would be nice. (hierarchical module names probably make this a
little more complicated somehow)
