================================

Caveat: the mixins defined with `define-eh-alternative-mixin` cannot be

provided and used in a separate module. Unfortunately, I cannot think of an

acceptable fix for this problem, as solving this would require extracting

parts of the mixin while preserving the bindings of some identifiers, but

altering the bindings of others. This means that for the foreseeable future,

once a mixin is defined, can only be used via `~mixin` (or by directly

invoking it) within the same module.

The regular and splicing syntax classes defined with `#:define-syntax-class`

and `#:define-splicing-syntax-class` will work fine across module boundaries,

however. Manually defined syntax classes, splicing syntax classes or

ellipsis-head syntax classes will also work fine across module boundaries,

even if they contain uses of `~no-order` and `~seq-no-order`, and even if

those special forms contain uses of mixins defined within the same module. In

other words, as long as a definition of a mixin and all its uses via `~mixin`

are within the same module, everything else should work without surprises.

Like https://github.com/AlexKnauth/seq-no-order, but provides global

constraints.  AlexKnauth's implementation allows dotted "rest" pattern which

this implementation does not support.

This package is unstable, and its API may change at any moment. Once it is

stable enough, it may be merged into [Alex Knauth's

implementation](https://github.com/AlexKnauth/seq-no-order).

The following pattern expanders (and mixin expanders, see the docs) for `syntax/parse` are defined:

* ~seq-no-order

* ~no-order

* ~post-check

* ~post-fail

* ~nop

* ~optional/else

* ~global-or

* ~global-and

* ~global-counter
