clone function in lib_oo cannot deep-copy a KOSDelegate that uses closures

[stevemeacham]

Problem:
Closure-referenced variables cannot be copied. Any closure-reference will forever refer to the same variable in the same memory location. This prevents deep copying of any KOSDelegate, or structure that contains a KOSDelegate.

If the closure-referenced variable is immutable (i.e. never changed after the closure is established), this is not a problem in practice. However, if the variable that is deep copied along with the KOSDelegate, the KOSDelegate will still refer to the original variable, not the copy.

As a workaround, only use closures to refer to immutable variables if the KOSDelegate could possibly be cloned().

The solution seems to be impossible in Kerboscript alone. Perhaps by modifying the .ksm byte-code? Perhaps by adding deep-copy semantics to Kerboscript itself that makes this work? I think that Rust can re-bind closures, for example.
