I'm taking a direction to use `dict[int, () -> Expr]` mapping because I think that the table is looked up also to find which key there is. And it is...

The other trick is to put each constants that are heavy to compute into separate modules, such that the python import system can cache the module.

I think that there is a flaw in the logic in https://github.com/sympy/sympy/blob/25e693689507dc705308c752605fb00f393888c8/sympy/core/relational.py#L426-L431 where the expression is evaluated numerically first and then the numeric error is compared symbolically. I try to...

Can the tests be added?

Can you try adding some tests?

Integral transform classes also naturally support the unevaluated objects like `LaplaceTransform(f(x), x, s)` where it can represent an algebra of unevaluated transforms.

Does this use `residue` for inverse transforms? Residues should allow direct inversion. I think that it could be good to check some applications and consistency between this and that.

I think that it also has the problem if it doesn't reach `'aa', 'aaa', 'aaaa', ...`

> @asmeurer Thank you. From my experience, the Lark-based LaTeX parser is significantly slower than the ANTLR one (unless I am missing something). Why exactly is it being considered for...

I'm a bit off about adding rules for `\sympyi`, `\sympytr`, `\sympyadj` because that is not recognized by mathjax, or katex. (and we don't want to complicate the machinery to deal...
