dlang/dub pull request #2098 "Fix #2085: [visuald] spurious library project"
was merged into master:

- d2e8c03f89c52b6b57d12449acb87e1b67cd831b by Bastiaan Veelo:
  If no output is generated (TargetType.none) then don't generate a project
configuration.

  This prevents VS from attempting to build a library with no name from no
sources.
  Fixes #2085.

Although bug 4075 appears similar to this one, the patch doesn't fix it.

Here's patch that invokes the semantic on the function if referenced.
Additioally, it needs to avoid duplicate semantic to be run later.

This patch also fixes #3499

This bug is hit regularly when porting C to D.
It's a shame that C macros don't suffer from this ordering bug :)

#define a b(0)
#define b(c) (c+1)

another example

enum { a=b() }
int b(){ return 0; }
