comment Shadowing of optional function arguments?
If you manage to hash it out, you can answer your own question, and I can offer comments if I see it fit to do so. :)

comment Is there a function equivalent to rewrite function in Sympy
Well, it's tricky with FullSimplify[]; not so much with FunctionExpand[].

But nothing beats seeing the examples for yourself. Study the Statistics` legacy packages as an example of using a Common.m package.

comment Shadowing of optional function arguments?
Unfortunately, as I am not writing this message from a computer with a proper Mathematica installation, I have refrained from writing an answer on this. Nevertheless: if you'll look at the LegacyPackages folder in your installation, you'll find package files in there named Common.m, where the shared symbols are declared. Then, in the package that will be using these shared symbols, there is an additional declaration in BeginPackage[] for the Common` context.

comment Shadowing of optional function arguments?
@FJRA, if you'll indulge me a rant: one peeve I've always had since Mathematica started using strings for options was that one cannot attach usage messages to strings, and thus one cannot use ? to learn more about them without having to refer to the docs.

comment Shadowing of optional function arguments?
The strategy done by the built-in packages was to declare symbols common to both packages in a Common` context.

comment Is there a function equivalent to rewrite function in Sympy
Well, not entirely. "rewrite trigonometric functions as complex exponentials" is covered by TrigToExp[], and "combinatorial functions as gamma functions" is done by FunctionExpand[].

comment How to count column occurrences in a matrix?
You can use Take[] to extract rows, Transpose[] to turn columns into rows, and then Tally[] to count occurences in rows.

Maybe a PatternSequence[]? That should be usable for checking neighbors…

"no neighbor to their left or their right" - that is, their difference from the numbers before or after them is greater than 1, yes?

We just enclose them in backticks (`), @David.

@David, you might be interested to know that VectorAngle[] is built-in…
