[Haskell-cafe] serialized data structures (Was: Generalized, named, and exportable default declarations)

[YueCompl]

I suggest it won't need to be as efficient as Text, just reasonable efficient will suffice. 

C++'s mantra of “you don’t pay for what you don’t use” is overly emphasizing on the machine aspect on today's stand point, as machine price (hardware purchase, energy consumption for the run, time to result) descending and human price (programmer / analyst / management mental overhead, time to production deployment, bug tracking & resolution, maintenance & service) ascending, more and more orgs will be willing to pay reasonably more on machines to save the cost on humans.

GHC / Haskell's unique trade off w.r.t. optimization may be the new sweet spot in coming years as I feel it.

What would happen if we invest equally much time into making String as efficient as Text? At ICFP 2019 I attended a talk about Gibbon:

Wouldn't this enable us to use String instead of Text, again, maybe even lists instead of Vectors? No more Text integration efforts, no more external library with GHC-specific manual optimizations. Unfortunately, the project is still in an early stage. So far, it only supports strict data structures.

There's been some disillusionment with the shortcut fusion, rule-based rewriting, and similar advanced techniques. It's probably been inevitable that, as GHC slowly shifts from research and teaching to industrial use, the community would get jaded with amazing but flukey research results and put more value on boring predictability instead. Unless Gibbon can make String perform *consistently* as efficient as Text, I don't see the project gaining adoption.
