How to assign a char in Xtend?

Question

How can a variable of type char be assigned? I am looking for the Xtend equivalent of javas:

char c='?';

In Xtend the compiler reject all quotation marks like ' or " because they produce a String:

var char c='?';

^ Error: Incompatible types. Expected char or java.lang.Character but was java.lang.String

Xtext Version is 2.2

Since 2.4 you can write:

val char c = '?'

Of what type is `c` when no type is specified? `val c='?'` – Chriss Mar 09 '13 at 19:15
Than it is still a String. – Sven Efftinge Mar 12 '13 at 19:38

Currently you have to use '?'.charAt(0).

Ohh... nice! I thought you are kidding, but you are a Xtext commiter, so i think the answer is credible. Is there a plan to get this fixed? – Chriss Jun 12 '12 at 10:35

Yes, we will adress this issue in the release after 2.3. I expect that to be available in autumn. – Sebastian Zarnekow Jun 12 '12 at 11:32
