Note: "<code>!!</code>" is not a no-op, but is a sufficiently uncommon expression one can use it.</p>

Powerful tools for writing and debugging R code. Provides: 'let()' which converts non-standard evaluation interfaces to
parametric standard evaluation interface, 'DebugFnW()' to capture function context on error for
debugging, and ':=' named map builder, and lambda-abstraction.
