I think this is a general problem of array and AA literals allocating at
runtime (and sometimes *every single time* the literal is used). We
really should have a way of generating array and AA literals in the
object file so that no runtime allocation is needed.

Runtime-generated literals really should only be used when there are
runtime variables involved in their construction, i.e., immutable x =
[1,2,y] can't be allocated at compile-time if y is a runtime variable,
but immutable x = [1,2,3] can and should be allocated at compile-time
and saved in the object file.
