Error on missing context variable

[BebeSparkelSparkel]

Is there a way to throw an error if there is a missing variable instead of defaulting to blank?

It would be useful to have a required syntax as a prefix to a variable name. Like $$!name$$

No, but you could write a function that walks the compiled template and compiles a list of variables, then use this to test against a Context.

I was thinking about that but it starts becoming more complex with the conditionals.
