Provides DebugFnW() to capture function context on error for
debugging, and let() which converts non-standard evaluation interfaces to
parametric standard evaluation interfaces.
DebugFnW() captures the calling function and arguments prior to the
call causing the exception, while
the classic options(error=dump.frames) form captures at the
moment of the exception
itself (thus function arguments may not be at their starting values).
let() rebinds (possibly unbound) names to names.
