    Breakpoint code instrumentation · 37610105

    Instrumentation gets activated by the '-fdebugging' dynflag.
    All the instrumentation occurrs in the desugarer; it consists of inserting 'breakpoint' combinators at a number of places in the AST, namely: 
     - Binding sites
     - Do-notation statements 
    These 'breakpoint' combinators will later be further desugared (at DsExpr) into ___Jump functions.
    For more info about this and all the ghci.debugger see the page at the GHC wiki:
