          Issue ID: 16340
           Summary: case where version(unittest) results in an invalid
                    warning about a dangling else
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com

This is a reduced version of some code that I've been working on:


void main()
{
}

version(unittest) template symsToStrs(fields...)
{
    static if(fields.length == 0)
        enum symsToStrs = ["hello"];
    else
        enum symsToStrs = ["world"];
}


Note that if you compile it with warnings enabled, you get something like

q.d(9): Warning: else is dangling, add { } after condition at q.d(5)

However, if you remove the version(unittest) from in front of the template,
then the warning goes away. Whether the code is compiled with -unittest doesn't
matter. But regardless, there is no dangling else here. So, the warning is
incorrect.

This issue looks similar to issue# 15326, but the code in that one doesn't have
this problem anymore, so it doesn't look like this is a regression of that bug,
though its cause may be similar.
