Hi Brooks,

Then, a couple of lines after that, there's the second definition for \frac, which is the one that needed patching. This one, unlike the first definition, is wrapped in \mathematics so that it can work outside math mode.

So I'm wondering why only \frac has this second definition that allows

it to work outside of math mode. I would think that things should be

consistent -- either that all of the definitions in the first list

should be changed to use \mathematics, or that \frac should be returned

to the simpler version -- so that \tfrac is still simply "\frac typeset

in text mode" as one would expect it to be.

`this has a historical reason; it was added because latex users expect \frac to be there and to work in text mode as well;`

Even if they're all left in the current form, I'd think that the unused

definition of \frac in the first list should be removed.

`well, just consider it not to be there; it should definitely not be mentioned in manuals -)`

My argument for simplifying \frac to take the \mathematics out of it is

that it is a math-mode construct that typesets its arguments in math

mode, and allowing it to be used outside of math mode encourages sloppy

TeXing. It also hides the point of transition to math mode, meaning

that x and \frac{1}{x} will typeset x differently, which strikes me as

confusing. I recognize that this is a very debatable position, though,

and that there are at the very least arguments for backwards

compatiblity that contradict it.

`if i remember right (maybe tobias burnus remembers more) it was mainly meant to be used in section titles; in such cases, when one sets a font explicitly, math is often not set up accordingly and frac permits one to do at least fractions`
