Having a lyxfunc take a stream argument has a major disadvantage: it
transforms a compile-time error into a runtime one. Having a template
class for lyxfunc's, as Lars initially proposed, won't compile if
someone feeds it the wrong arguments. I'm talking developers here,
not users. Catching programming errors during the build is much
easier to debug than runtime errors.
This leaves only parsing the minibuffer/keybinding defns. for runtime
errors. That parsing, however, can perform typechecking before
calling the actual lyxfunc.
