           Summary: Support a unit test handler
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: jason.james.house at gmail.com


I'd like to see a way for the D language to push unit test handling into an
external library.  If a unit test is treated as a delegate, it can then boil
down to a single call to a unit test handler.

I'd suggest using any args of the unit test to be arguments into whatever unit
test handler exists.  This would allow use of special libraries built to
leverage an already existing unit testing framework.

Example:

source:
unittest("My test name"){ ... }

... causes the compiler to call:
void unitTestHandler(delegate void dg(), char[])
