* [testament] --verboseMegatest flag to make megatest compilation verbose
* replace "tests" by testsDir
* megatest's nimcache is now in same dir as other tests to avoid clobbering (eg when running tests from multiple Nim repos)
* as instructed in #2353, provides a short description why
there are no specialized procs for seq[Rune]
* adds several examples to better explain what some functions do
* small fixes (double backticks, add missing dots, etc.)
* use `rune` instead of "unicode characer"
* Resolve things raised in https://github.com/nim-lang/Nim/issues/10081 ?
CDF is a standard ident in all things related to random numbers/sampling,
and full words "cumulativeDistributionFunction" would be silly long, in
this case, IMO. We use lowercase `cdf` to make it not look like a type,
remove all looping from `sample` letting callers do it. Besides just
side-stepping any `sampleSize` name choice, callers may want to filter
out samples anyway which this makes slightly simpler.
Also add two variants of `cumsum`, value return and in-place update
distinguished by the var-ness of the first argument. Add tests for
`int` and `float` for both `cumsum` and the new `sample`. (The sample
tests exercise the value return mode of `cumsum`.)
Functionality pre-this-PR `sample(a, w)` is now the almost as simple
`for i in 0..<n: sample(a, w.cumsum)`, but this new code factoring is
almost surely better. The statistical tests pass, as before.
* Address Araq comment in https://github.com/nim-lang/Nim/pull/10084
We can always add in some `var` version later if desired to save
memory, but this change now at least firms up the `sample` interface.
* Rename `cumsum` -> `cumsummed` to honor NEP1 style. Re-instate `cumsum` as
the in-place transformation. Test both in `tests/stdlib/tmath.nim` and use
`cumsummed` in the example code for sample since that's a simpler example.
* Fix requests from https://github.com/nim-lang/Nim/pull/10084 :
example in lib/pure/math.nim and comment whitespace in lib/pure/random.nim
* Move typetraits.`$` to system. Fixes#5827.
* revive PR; adjust code to make sure everything works and add tests
* fix tests/concepts/tstackconcept.nim
* address comments
* Give deprecation warning when type pragmas do not follow the type name
* pragma before generic parameter list in type definition is now deprecated
* Update changelog
* Fix bug where deprecated warning was being shown even though no generic param list was present
* Fix bug
* Use errGenerated
* Best attempt at writing the grammar
