Hmm. This seems to be a tricky corner case. The delegate itself
is impure, as it accesses y which is outside of its definition
and isn't part of its arguments; however, in the larger context
of spam(), this shouldn't be a problem since y is accessed via
'this', and 'this' is part of spam's input.
Isn't it okay for pure functions to access global immutable
state, such as what the delegate is doing here?
