I don't want to use lambda.
I don't want create variable.

What is the best way to refer to itself when obtaining Substring withou using lambda and without create variable?


example:

writeln("Hello Word!"[x.indexOf(" "), $]);

alias Seq = AliasSeq!("Hello Word!"); // it isn't a variable, lambda or enum
writeln(Seq[0][Seq[0].indexOf(" "), $]);

looks weird anyway

Maybe u want this?

import std.stdio: writeln;

"Hello World".find(" ").writeln;

What a pity! If Dlang have $ to indicate end of string. I think that is good some keyword to indicate the string itself.
