Being compiled is not necessary to be able to self-reference
everything. Haskell and Clean are usually compiled, but when they are
interpreted, they work the same way: because they use lazy evaluation,
it's normal to have every name defined in a group visible in all
the bodies.

This applies to all value definitions, not only to functions, even if
it's nonsensical, i.e. 'let x = y+1; y = x+1 in x' is only a runtime
error or an infinite loop.
