In the title: Because "typeof" is a keyword,it does not have the same semantics
as the other properties (http://dlang.org/property.html), such as stringof,
sizeof etc..

For example:
--------
void main()
{
    int a;
    writeln(int.stringof);
    writeln(a.typeof.stringof); //This
    writeln(typeof(a).stringof);
}
--------
The syntax "a.typeof.stringof" should be made to work.

UFCS should not have a different behavior because typeof is a keyword.

typeof isn't a function, nor is it a property. It's a built-in construct like
is-expressions are. Would you want is-expressions to work with UFCS as well?

No, I think that this is trying to take UFCS too far.

Why is this taking it too far? In the duplicate you also 
expressed reservations about it without explaining why it's a bad 
idea. UFCS seems very much like the natural evolution of D's 
syntax and once (if) that's accepted it should be as consistent 
and general as possible.

See my Issue 4272 I think "a.typeof" is a nice syntax to have, similar to "a.sizeof". But this isn't an example of UFCS. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Yeah... I should have opened it as ER, not Bug.

You are right, "nice to have". I searched if it existed before, but did not
find your issue. Closing as duplicate.

*** This issue has been marked as a duplicate of issue 4272 ***
