Hi Rudolf,

I feel the need to point out that this way lies madness.

The behaviour of $ in Org is /inherrently/ confusing. You’re confused by `$...$th'
and `$...$-th'. Say those were special-cased, somebody notices the work and then
try `$n$-dimensional' and now are /even more confused/ when it doesn’t work.

Ok, say we make `$...$' just apply in more cases, then we have somebody who
writing about prices who changed `$3 or =$5' to `$3-$5' and now “weird things are

The root issue is the way that `$' tries to pull double-duty as both a literal `$'
and a delimiter. It’s all very well to say that “in LaTeX this is fine”, however
in LaTeX this /simply is not an issue/* as single dollars must be escaped as `\$'.

We can fiddle with the heuristics, but there is no perfect solution here …
other than to move away from `$' and prioritise `\( ... \)' in our documentation and
examples, even add a linter rule that raises warnings about the tendency of
dollar-math to misbehave when people use it.

All the best,

* It’s still a pain/discouraged for other reasons.
