(No, it is not.)
From the DIP:
"This proposal sustains that optional parentheses should stay in. That
means, if a function or method may be called without arguments, the
trailing parens may be omitted. [...] The same goes about methods: [...]
However, that's not the case with function objects, delegate objects, or
objects that implement the function call operator. [...]"
Should also mention static opCall.
The section does not mention what happens with first class callables
that are invoked via UFCS. In particular, the validity of eg. the
following code (which currently is valid) is not specified:
enum foo = (int x)=>x;
static assert(2==2.foo);
