What is more strange is that a = a + 1 and a = 1 + a are somehow distinct. The second give a stack overflow almost instanly, but the first don't.
That's because what the runtime does looks in the second case like a = 1 + 1 + 1 + 1 + 1 + ... + a ... and the first like a = a = a = a = a = a = a = ... = 1 + a , which is a much more space efficient endless loop. That's not specified though, the runtime could choose to let + force the two chunks the different way round. -- (c) this sig last receiving data processing entity.
