Extended core library for Clojure/Script that emphasizes:
  * Cross-platform API
  * Flexibility
  * Performance
  * Backwards compatibility

This lib's mostly for my own use and for advanced users that feel
comfortable reading this source. Not providing much beginner-oriented
documentation for this, sorry.

Common naming conventions used across my libs:
  **foo** - Dynamic var
  foo!    - Fn with side-effects, or that should otherwise be used cautiously
  foo?    - Truthy val or fn that returns truthy val
  foo!?   - Fn that has side-effects (or requires caution) and that return
            a truthy val. Note: !?, not ?!
  foo$    - Fn that's notably expensive to compute (e.g. hits db)
  foo_    - Derefable val (e.g. atom, volatile, delay, etc.)
  foo__   - Derefable in a derefable (e.g. delay in an atom), etc.
  _       - Unnamed val
  _foo    - Named but unused val
  ?foo    - Optional val (emphasize that val may be nil)
  foo*    - A variation of `foo` (e.g. `foo*` macro vs `foo` fn)
  foo'    - ''
  -foo    - Public implementation detail or intermediate (e.g. uncoerced) val
  >foo    - Val "to   foo" (e.g. >sender, >host), or fn to  put/coerce/transform
  <foo    - Val "from foo" (e.g. <sender, <host), or fn to take/coerce/transform
  ->foo   - Fn to put/coerce/transform

Type affixes may be used for clarity:
  <prefix>-<name>  - m-users,   v-users,   n-users,    etc. (also nusers when unambiguous)
  <name>-<postfix> - users-map, users-vec, user-count, etc.

Regarding name heirarchy:
  When there's a significant num of syms with a meaningful hierarchy,
  prefer names with descending hierarchy to emphasize structure and
  related groups/functionality, e.g.:
    `user-add`, `user-remove`, `user-mod` vs
    `add-user`, `remove-user`, `mod-user`, etc.

Commit message tags (in priority order):
  [wip]   - Work-in-progress (still under development)

  [mod]   - Modify     behaviour (=>          breaking), [mod!], [mod!!], etc. for attention
  [fix]   - Fix broken behaviour (=> usu. non-breaking)
  [new]   - Add new    behaviour (=>      non-breaking)

  [doc]   - Documentation changes besides those better labelled as [mod], [fix], or [new]
  [nop]   - Other non-breaking changes (to implementation details, non-code changes, etc.)

  [x] [y] - Single commit with multiple tags (in priority order), try avoid
