Support for rules containing MathConstants

Many mathematical equations involve numbers such as pi, Euler's constant and the golden ratio. Currently, Symbolics does not seem to handle `AbstractIrrational` well. Expressions like `sin(2π+x)` can not be simplified.

Support for categorical factors and discrete numeric factors

I use Surrogates.jl quite often for chemical reaction optimization. Everything goes well, as long as only continuous process factors, such as temperatures, pressures and concentrations are involved. However, almost invariably...

Tutorial BlockDiagonals

Does LinearSolve.jl specialize automatically with BlockDiagonals.jl? If so, it might be worth a tutorial to showcase this functionality.

the symmetry of the hessian is exploited for extra compression (casadi also does this): https://github.com/JuliaDiff/SparseDiffTools.jl/blob/master/test/test_sparse_hessian.jl#L12 But I don't immediately see how that extra compression is then later recovered: https://github.com/JuliaDiff/SparseDiffTools.jl/blob/master/src/differentiation/compute_hessian_ad.jl#L142 ```jl...

Start fixing CI

The CI in some of the repos does not do anything, e.g. https://github.com/SciML/SciMLOperators.jl/actions/runs/3119548680/jobs/5059578239#step:6:194 This is because there is insufficient control flow for `GROUP`. It is not clear to me how...

For non standard window sizes the buttons overlap: 

Aqua finds quite a few places where quality could be improved, I'm going to need help from the maintainers to resolve these issues.

Such that `makedocs` `warnonly = [:docs_block, :missing_docs, :cross_references]` can be removed.

Aqua + typos CI

I don't understand the unbound args error in this one.
