A coding pattern: a global "whatever" referencing a local "whatever

I’m sure this has been shown somewhere before. What it may have been called, danged if I can figure it out.

Sometimes, I do not want to bother with macro parameters. Instead, I’ll have a global macro reference a macro that needs to be defined by the tiddler that is referencing the global macro.

To keep the code short and sweet, this is a brutally silly example for demo purposes.
