It seems there's enough interest to make it official. The usual two-week
period begins now.

Intersperse can be given very pleasant performance characteristics for
sequences: the result can constructed incrementally as it is consumed.
Intercalate cannot perform so pleasantly, but it seems odd to add one but
not the other.
