I think its good to point out that it is possible to
differentiate between one-time-expressions
and compile-time expressions. I think an expression
executed once, however, not at compile time can make
a pretty good lazy initializer in the sense you mentioned.
  Alas, I must admit that I’m not aware of an example that
cannot be equally good expressed with the …ifNil: variant 
as with the [] once  variant.
