[racket-dev] provide expand-clause in racket/private/for.rkt

[Stephen Chang]

Hi dev,

I would like to provide (for-syntax) the "expand-clause" function in
racket/private/for.rkt. Would this cause any problems? Would anyone
object to this?

I have an implementation of for/X in my generic-bind library that uses
expand-clause and with it, the generic-bind ~for forms are as fast,
sometimes a little faster, than racket's for/X in some preliminary
testing. (Without access to expand-clause, sequence traversal is slow
--- the current planet-available version of my library uses
sequence-generate and is twice as slow.)

The "sometimes a little faster" is likely in part due to less
error-checking, but my implementation passes all the for/X unit tests
and so as is, it can reasonably be used in place of for/X.

Yes, the intention there is to run the tests individually but test that the
"all runner" works

That means that it is disabled, probably because it was intended to just
run each file separately

Whether DrDr runs a file is different on a file-by-file basis via the props
database. For this file...
