How to compile in earlier versions using new keywords?

[Alex Tweedly]

I have to admit that when I first saw this solution, I thought "hmmm - 
clever but feels like it is exploiting a loophole". Depending on the 
engne to quietly ignore error-containing stacks just "feels wrong".

I have NOT tried it, but a conceptually cleaner (to me) solution would 
be to have a "splash-stack" approach, where the splash stack would 
determine the major version in use, then load any behaviour stacks (i.e. 
dependent on the version number if appropriate) and then finally load 
the app stack, so that the version-dependent behaviours would come into 
play. (I haven't been paying enough attention to know whether it would 
need to "re-bind" the behaviours or not.)

If we had the latter it might make it very hard to fix some issues. Additionally the engine will load a stack file that has uncompilable scripts silently. At some point it might be helpful to get a list of issues popping up at which point my solution won’t be a good idea so I would switch to dynamically switching behaviors depending on the version.
