It is used for macros with arguments. Each argument of a math macro is one cell of the macro. An ArgumentProxy is the expanded representation of such a cell. It has basically no own data (except for a possible default argument), but forwards everything interesting to the macro itself. The only reason why it is needed is reusage of some MathData member functions: draw(), metrics, dimension() etc. > BTW updateMacros is quite heavy on big documents (#5973) and I have > medium-term plans for making the update lazy.

I know that this needs work, but I don't see an obvious miracle:-( Currently we also have the strange mixture of lazy and non-lazy macros. Georg
