First draft of translation document

[Peter Levart]

Hello Brian,

Good work.

Just a note on section "10. Multiple lambdas per scope". While this approach is logically correct and optimizes the number of Objects created/classes used, it has a drawback that it might introduce memory leaks. A long-lived lambda might hold on to the references that it didn't actually capture in the source code.

To remedy this, the set of mutable variables S captured in the same scope by multiple lambdas where each lambda (Li; i=1..n) captures it's own subset (Si; i=1..n) would in general have to be broken into at most 2^n-1 disjunctive non-empty subsets (much less in common cases) and a separate frame object created for each of them.

Regards, Peter
