1154	error using 'bindings' egg from an 'included' script	John Foerch	sjamaan	"The setup for this error is to have one script that includes another script, and the second script has (use bindings) and some use of the forms provided by the bindings egg.  For example:

######### test-case.scm

    (import chicken scheme)

    (use extras)

    (include ""script-that-uses-bindings.scm"")


######### script-that-uses-bindings.scm

    (use bindings)

    (pp (bind (a b c) (list 1 2 3) (list c b a)))


run with: csi -s test-case.scm

This resulted in the following error:

    Error: during expansion of (dbind21 ...) - unbound variable: macro-helpers#seq-destruc

If you use 'load' instead of 'include', there is no error.  Also if the first script (test-case.scm) does (use bindings) there is no error.

I tested this with Chicken 4.8.0.3 and bindings egg version 3.1.  Another person reported that they could reproduce the error with Chicken 4.9 as well.
