Believe it or not, but this can result in the function being
called. This is D's optional parenthesis feature, to do simple
property syntax.
Not a bug.
I want get the function name "t2", "t3" for string mixin, how
do I do this in D ?
You should never actually need that! What is your use case?
In most cases I see people doing .stringof, the correct solution
is to simply... not. Use the local name directly.
If you do need the name - and the only cases for this ought to be
declaring a new item for public consumption or for interfacing
with users - the correct way to get an identifier is
`__traits(identifier, T)`... but again, more often than not, you
do NOT need this and it is wrong to try!
.stringof should almost never be used except for debugging, and
string concatenation in string mixings is actually only necessary
for new declaration names.
OK:
mixin("int " ~ name ~ " = T;");
Wrong:
mixin("int " ~ name ~ " = " ~ T.stringof ~ ";");
