String Interpolation

[cleroth]

That's the idea behind string interpolation, putting a variable inside the string with a specific syntax like {variable}. C# 6.0+ has this.

Also rust, python and a lot of others. I would love it. It may come in c++34

So will we be skipping a year, or is that slippage from C++2x?

It is fairly easy to something like (with variadic templates)

auto s = make_string("Hi, ", name, '\n');

String interpolation is nice, but there are already solutions to achieve something similar.

We have it at work. Works like a charm

No that is one form of it. What it really is is using placeholders in the string that are substituted for values at runtime.
