Yes, with value semantics.

Reset the label to an empty string and let the write/whatever method handle that case. There is no "empty MathAtom" and so far I resisted the tempatation to make that possible. If we really need 'one or zero', MathArray would be the way to go. But I doubt this is possible, as the empty label string can serve the same purpose. > Could you provide me with a broad-brush outline of what you think needs > to be done. Uh, I think this is none of the most pressing problems right now... [Just in case you ask what _is_ pressing: Line breaking in ParInset and multicolumn for TabularInset are much more important...] If you want to play with IU a bit you could look at math_tabularinset/math_gridinset and make it work with the tabular dialog ;-) Andre' -- Those who desire to give up Freedom in order to gain Security, will not have, nor do they deserve, either one.
