           Summary: Template with enumerated constant length array causes
                    error.

Example D2 code to generate the error together with what causes it.

When foo function is used, compile time error is seen.

bugtesr.d(16): Error: template bugtesr.Test.foo does not match any function
template declaration. Candidates are:
bugtesr.d(4):        bugtesr.Test.foo(T)(in T[Test.DATA_LENGTH] msg) if (is(T :
ubyte) || is(T : char))
bugtesr.d(16): Error: template bugtesr.Test.foo(T)(in T[Test.DATA_LENGTH] msg)
if (is(T : ubyte) || is(T : char)) cannot deduce template function from
argument types !()(ubyte[16])


If the constant DATA_LENGTH is replaced with its real value 16, it works
without a problem.
