* :iterate -- repeatedly evaluate and bind to the expression while it is
truthy.
* :range -- loop over a range. The object should be a two-element tuple with
a start and end value, and an optional positive step. The range is half
open, [start, end).
* :range-to -- same as :range, but the range is inclusive [start, end].
* :down -- loop over a range, stepping downwards. The object should be a
two-element tuple with a start and (exclusive) end value, and an optional
(positive!) step size.
* :down-to -- same as :down, but the range is inclusive [start, end].
* :keys -- iterate over the keys in a data structure.
* :pairs -- iterate over the key-value pairs as tuples in a data structure.
* :in -- iterate over the values in a data structure or fiber.
`loop` also accepts conditionals to refine the looping further. Conditionals are of

where `:modifier` is one of a set of keywords, and `argument` is keyword-dependent.
`:modifier` can be one of:
* `:while expression` - breaks from the loop if `expression` is falsey.
* `:until expression` - breaks from the loop if `expression` is truthy.
* `:let bindings` - defines bindings inside the loop as passed to the `let` macro.
* `:before form` - evaluates a form for a side effect before the next inner loop.
* `:after form` - same as `:before`, but the side effect happens after the next inner loop.
* `:repeat n` - repeats the next inner loop `n` times.
* `:when condition` - only evaluates the loop body when condition is true.

The `loop` macro always evaluates to nil.
