Beware of silver bullets.

Except that it is still possible in most cases. For example the JRuby JIT + Java JIT will optimise various paths and functions and keep these optimised versions around until the "environment" changes. In that case it stops the world, throws away the old compiled units and create new ones taking into account the current situation. In practical terms this means that using `eval` works flawlessly but kills your performance.
