I'm not sure to what extent this is a LaTeX bug... That breaks because `\MakeUpperacase` does an `\edef` in its argument, then `\hyper@linkstart` explodes, but `\MakeUppercase` hasn't changed recently, so...

@bastien-roucaries TeX accepts multiple signs in front of a number, so your test is usually enough but not always. Should this be implemented, it could allow multiple signs like this:...

@bastien-roucaries The biggest integer TeX can handle: 2³¹−1 = 2147483647.

@bastien-roucaries `\romannumeral` only breaks with “Number too big” for a nonzero number. TeX can take an arbitrarily long string of zeros as long as the resulting integer is within the...

It'd be better to implement it as a boolean key: ```latex log-functions .choice: , log-functions / true .code:n = { \sys_load_debug: \debug_on:n { log-functions } } , log-functions / false...

@eg9 Well, yes, we could change the documentation and say that `log-functions` only turns logging on, but to me the name `log-functions` calls for a true/false value, and it's no...

> but you can't turn it off (nobody does that but) you can by doing `\sys_load_debug: \debug_on:n { log-functions }` then turning it off again by loading the package. But...

Not only the footnote goes to the wrong place, but also the inner minipage inherits the width of the outer one, resulting in an overfull box. Adding `\setbox\@mpfootins\box\voidb@x` to the...

@u-fischer Oh :/ The code for `\@mpfootnotetext` globally sets `\@mpfootins`, so my local `\setbox\@mpfootins\box\voidb@x` won't work. I suspect that the reason for that assignment to be global is that both...
