           Summary: Templates can't take function pointer parameters
           Product: D
           Version: 2.012
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: rejects-valid
          Severity: normal

dmd 2.012, Linux

dmd rejects code which the spec says should be valid (the spec doesn't mention
any limitations to value parameters):

BEGIN CODE
  template foo(void function() fp /*TPL...*/) {}
  void bar() {}
  alias foo!(&bar) a1;
END CODE

BEGIN dmd OUTPUT
  test.d(1): Error: arithmetic/string type expected for value-parameter, not
void function()
END OUTPUT

BEGIN CODE (2nd manifestation)
  template foo(TPL...) {}
  void bar() {}
  alias foo!(&bar) a1;
END CODE

BEGIN dmd OUTPUT
  test.d(3): Error: expression & bar is not a valid template value argument
  test.d(3): template instance test.foo!(& bar) error instantiating
END OUTPUT

This has just cropped up on IRC.  Either the compiler should be fixed to match
the spec, or the spec should be changed to match the compiler's behaviour.

The simplest thing to do would be to change to spec to indicate that only
strings, ints and floats are allowed as value parameters.
