Various repairs --- especially to avoid duplicated prose.
Instead of
@(define explain @t{Long explanation about X...})
@defproc[(a ....) ....]{ .... @|explain| }
@defproc[(b ....) ....]{ .... @|explain| }
@defproc[(c ....) ....]{ .... @|explain| }
write
@defproc[(a ....) ....]{ .... Long explanation about X ... }
@defproc[(b ....) ....]{ .... X is like @racket[a]. }
@defproc[(c ....) ....]{ .... X is like @racket[a]. }
Otherwise, a reader is forced to reverse-engineer the
abstraction underlying `a', `b', and `c'.
The properties appear in the inlining expansion of an application
of a keyword-accepting function, and they're mainly intended for
use by Typed Racket.
The property keys are hidden, so that the property value can be
trusted as originating from `racket/base'. The accessor functions are
`syntax-procedure-alias-property' and
`syntax-procedure-converted-arguments-property' from
`racket/keyword-transform'.
In consultation with Ryan. We'd prefer to have versions of all
useful things in a `racket/...' library that is consistent as
possible with Racket forms and conventions.
This reverts commit f3b687c8ed.
After discussion with Robby and Stevie, we concluded that
this procedure isn't necessary for now. If we ever think
of more examples where it's useful we can bring it back.
a chaperone contract", "no it definitely isn't" or "evaluate this code
at runtime to find out"; previously only the first two options
were available to opters
(this commit also includes other tweaks here and there so won't stand alone)
These primitives atomically update a box to a new value, as long
as the current value is the same as a provided value. They also
are future-safe.
When futures are enabled, they use low-level hardware instructions
to perform the change atomically.
The example relied on the current code inspector affecting
syntax object created during `eval', but since the switch
from certificates to taints, the relevant code inspector is
determined by the namespace, and a namespace gets its code
inspector at creation time.

The preserved path is exposed by a new `module-path-index-submodule'
function, and `module-path-index-join' now accepts an optional
submodule path.
Also, fixed a problem with `collapse-module-path-index' when
a module path indx is built on a resolved module path that
is a submodule path.
In addition to the main repair, `collapse-module-path[-index]' is
correctly documented to allow '(quote <sym>) rel-to paths.
Finally, `collapse-module-path-index' changed to use a symbolic
resolved module path that appears as the base of a module path
index, rather than falling back to the given rel-to path. It's
possble that the old beavior was intentional, but it wasn't tested,
and it seems more likely to have been a bug.
