Using delimiters for numeric literals in C# 7.0

Say you need to work with relatively large numbers in your C# code:

int number = 3452123;

Wouldn’t it be nice if you could use some kind of delimiter to indicate the millions, thousands etc? Like in 3,452,123? In C# 7.0 the underscore provides a solution for this:

int number = 3_452_123;

The underscores will be ignored by the compiler.
