           Summary: Typedef of an alias in another module used as template
                    parameter combined with circular imports fails strangely
           Product: D
           Version: 1.00
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: minor
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: deewiant gmail.com


A bug quite hard to summarize understandably. The code may help:

--
module aliasesType;

alias int myAlias;
--
module definesType;
import aliasesType;
import usesType; // creates the import cycle

typedef myAlias myTypedef;
--
module usesType;
import definesType;

template T(x) {}

// just use T with myTypedef somehow, doesn't matter what this is
mixin T!(myTypedef);
--

Compiling the definesType module results in the error "definesType.d(5): Error:
identifier 'myAlias' is not defined". Using the fully qualified name
"aliasesType.myAlias" instead fixes this error.

Did some more testing, and apparently it doesn't matter whether either is
specifically a typedef or an alias.

I could not reproduce this bug with DMD 1.047 and DMD 2.032.

Right you are, this seems to have been fixed at some point.
