Re: Proposal: add intersperse and intercalate to Data.Sequence

I guess you're talking about a situation where the annotations are somehow compatible, so that you can try to reuse them somehow? I'm not sure if that would work or not, but it's very far from true for sequences. On Dec 27, 2014 3:54 PM, "Edward Kmett" wrote:

Interestingly, it strikes me that the fingertree version of intercalate could be made more efficient, even if the sequence version can't.

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.
