To add something that exists in C# and other languages:

procedure Log(params Values: List of [Text])

Where you could pass in as many values as you want when calling the function

Log('123');

Log('123', '456');

Log('123', '456', '789');

And all of them would map back into the list. This type of pattern has been used inside the inner BC functions since the beginning of it. E.g., SetFilter('%1 %2 %3', 'One', 'Two', 'Three'); can pass in as many parameters as you want.

There are good use-cases for this, from mapping information to logging.
