I don't think your comment above is correct.
assert => aasert aseert azzert essert assort
all have the same overall length and shape.
Not all spelling errors are typos (hitting the wrong key). I've seen
spelling errors this bad, or worse, from native English writers. Poor
spelling, bad keyboards, distraction, and dyslexia can all contribute.
And those who aren't fluent in English will make their own spelling
errors, and may not even notice if the length of the word changes:
assert => asert
For those who are dyslexic, there are spelling errors and typos that may
be difficult to tell apart even though the shape of the word changes:
assert => assery asserh
(perhaps -- I'm not dyslexic, I'm just going by what I've read about
In my opinion, this sets a bad precedent for adding special case after
special case, and the risk is that people will feel slighted if they are
told that their typos aren't important enough to be made a special case
If Michael wishes to argue that this is a useful feature rather than an
ugly DWIM wart, that's his perogative, but the justification that
"assret" is the *only* such plausible typo is just plain wrong. We've
already heard from Robert Collins that he found a bunch of silently
failing assertions in his mocks, and none of them started with "assret".
