Well said. That is also a major concern of Graham and myself.
And it is not just people considering adopting Haskell
who are being annoyed, but also long-standing members of
the community.

Just to give one data point, Graham tells me that the
latest revision of Richard Bird's Haskell book was
broken with respect to the latest changes before it
had had a chance to hit the shops. The changes that
broke the book may well have been essential. But such
breakage is clearly annoying to many people, including
those who have bought a recently updated book only
to find that it does not quite work.

We really need to be careful to not break things
unless absolutely necessary.

Best,

/Henrik
