Improve coalescing of dynamic breakpoints in the ghci debugger
(or disable it altogether)
Right now coalescing of breakpoints works at instrumentation time by:
- Not inserting a breakpoint if there are no local bindings in the site
- Removing adjacent breakpoints, i.e. removing one of them (not implemented yet)
- adhoc case: if we are about to insert a breakpoint but the subexpresion is a HsLet, then don't.
Proposal is to disable cases 1 and 3 and implement case 2 using rewriting rules.
