digitalmars.D.learn - Template conflict with Function

reply Matthias Walter <walter mail.math.uni-magdeburg.de> writes:
Hello,

I've got another question regarding templates. I have the following functions:

int foo (int i)
{

}

int foo (T, U) (inout Expression !(T, U) expr)
{

}

The compiler stops with error: "template Test.foo(T,U) conflicts with function
Test.foo at Test.d(191)".

I'd like to call them in the following way:

foo (10);
Expression !(long, int) x;
foo (x);

I also cannot put them into one function template, because the parameter
storage class es differ.

best regards

Re-write the first one as:

int foo()(int i) {
}

That is, make it another, second function template, with no template 
parameters.

If not already present, I think this little trick deserves to go into the D
docs :-)

Until then there's always the Comments wiki page.
