And? The developers of Haskell owe us nothing. I don't see the point of your complaint. If the tool doesn't fit the bill, don't use it.

IMO Haskell is more of a dream project of having a highly optimizable and flexible complier. Its fun to write, great when it works (well), but it's not the workhorse of C and Python.

This is a pretty hyperbolic take imo.

Anecdata, but I've seen more space leaks in non-Haskell languages than Haskell in production despite having more production years of experience in Haskell over the last decade.

Space leaks really are not a big issue.

You have to understand runtime of any language in order to write memory-efficient code in it. Lazy runtimes are predictable once you know how they work.

It's somewhat telling that the first comment on a blog post about having control of laziness is about how "we struggle to control laziness" .. seemingly using the blog post's existence as proof that we don't have control?
