Re: Syntax sugar question

[Nikolay Kudryavtsev]

Be aware that you can do (foo-mode -1) to disable foo-mode, so the 
current behavior already has some complexity.

Syntactically if we start allowing parameter passage during the mode 
command, why stop at 1? Why not allow arbitrary number of params? I 
think the current design is fine as it is forcing every mode to work out 
of box. If people would start passing params, there would eventually be 
modes that would only work if you have a legit parameter declaration.
