Simple case - works now.
 boolean x = true;
 String answer = (x ? "yes" : "no");

Complex case:
Create special syntax for template processing inside strings - I guess
this can be a library issue.
We have jsr223. May be good ideaa is adding helper methods, which process
string via choosed language interptreter, i.e.
 .... but - from other side  we can't receive binding between names and
values automatically for now.

So, will think.  For me, approach is interesting, but I have more
questions than answers.

I guess this can be nice small new proposal, if think about ## as not part
of literal, but unary operator.

Btw - interessting, why nobody fire 'simple operator overloading' proposal
yet ?
