That works and it is probably the best thing I can do right now. (Or
go with a defmacro, which also seems to work). I should say that I am
using an older kawa for this. Maybe this is fixed in the newest
versions.
The reason to not remove the (require <request>) from <use> is that
then <macro> has to import and re-export all of <request>, for those
who might need it. But what about those who don't want it? And the
maintainer of <macro> has to watch <request> and make sure he is always
re-exporting all the bindings. (I usually use module-export to keep
some bindings private).
In general you'd like to be able to do the following, even if
MyAppHelp.scm defines a macro using Utilities.scm.
MyApp.scm ---------------------------------> Utilities.scm
\---------> MyAppHelp.scm ------->-----/

This works in the sample, but in the real code <request> is a utility
layer that I am trying to build <macro> on top of.
