I'm trying to learn how to restrict where expressions appear. Those expressions might be procedure applications, or macros before expansion.
[1] shows a library I use to help me implement a collection pass for a module language. To save you some reading, it uses syntax-parse with a lengthy #:datum-literals. That's the only way I know how to restrict what expressions appear in module context. One element of the #:datum-literals happens to share an identifier with a bound procedure, so I expand the calls as-is in a module-level expression [2][3]. I want that procedure to be applied ONLY in the module context, but nothing in the language enforces that. I don't know what I don't know. Could I please get a link to a part of the documentation that teaches me what I need to understand? I'm tied between querying syntax properties for a fully expanded module, and writing a second set of macros that somehow know where they should be. Not sure which is best.
