Well, one way would be to require a directive at the head of every file
saying (for example)
Haskell 1.4
And then compilers could always say "Not interested in compiling
Haskell 1.4 programmes"...
I don't think I like this though: it's an extra feature, and the whole
point of the standardisation effort is to replace features by
orthogonality (I hope).
