catching undeclared methods in a CommandMap

[Peter Krautzberger]

While writing a third party extensions, I did something like

new CommandMap(
    'my-macros',
    {
        bigsqcap: ['Macro', '\\mmlToken{mo}{\u2a05}'],
... 
   },
   Mymethods
);

But I had forgotten something like Mymethods.Macro = BaseMethods.Macro;

Typescript compiled without errors and running the extension just gave me an "unknown macro" error, without any hint as to what went wrong.

I'm wondering if there could more additional feedback in such a situation.
