Short description:

Allow the building of string with placeholders and variables:
"Hello {0}, you have {1} new messages."
Then pass in variables.
If it could accept multiple variable cards that would be nice.

no more than 10 would normally needed but even then you can just concat more.

Should be trivial to implement with a fixed number of variables, but a bit more tricky with a variable number of variables (but a list could work here).

If considered to make a .NET style string format operator
here is the .NET string class and format function
