The `GHC.Exts` module exports functions
[[http://hackage.haskell.org/package/base-4.6.0.1/docs/GHC-
Exts.html#g:6|breakpoint and breakpointCond]]. Right now they are no-ops,
but apparently at some point in the past could be used to set breakpoints
programmatically. From my reading of the source code, this feature was
removed (either accidentally or on purpose) when the implementation of
breakpoints [[changeset:cdce647711c0f46f5799b24de087622cb77e647f/ghc|was
reworked]].
