Debugging all callers of a function?

[jackfirth]

Sometimes I don't want to debug an expression, I want to debug all calls to a particular function. Would that belong in this package or a different library?

I'm imagining something like define/debug that works just like define but acts as if all callsites are wrapped in #R.

That would fit fine in this package. Although it won't be able to print out the expression of the callsite like #R would, and I'm not sure how a user would find which call it came from... If we do this, should define/debug define a function-like macro (sort of like rackunit does) so that it can save the source location and the expression?

[jackfirth]

I think a function-like macro like rackunit checks is a fine idea. Here's an idea for naming:

• (define#R (foo arg ...) body ...) Records callsite information in the same way as wrapping callsites with #R
• (define#RR (foo arg ...) body ...) Callsites recorded with #RR
• (define#RRR (foo arg ...) body ...) Callsites recorded with #RRR

define/debug seems too long to type.
