Hello,
dmd has a helpful feature, trying to guess which id may have been wrongly typed
-- provided the error actually was a typo:
__trials__.d(20): Error: undefined identifier goo, did you mean
variable foo?
But in numerous cases, the source of the error is not a typo, which leads to
confusing messages such as:
__trials__.d(19): Error: undefined identifier i, did you mean alias to?
I have no idea how dmd guesses possible names. But surely there is a kind of
probability evaluation used to rank possible guesses. If I'm right, then dmd
should not output its best guess in every case, but only when its probability
value is higher than a given threshold (to be carefully defines).
Also, the case above probably reveals some kind of bug, since it is hard to
imagine how "to" can ever be the best guess for "i" (and there is no alias in
the test case). PS: "alias to" is only guessed when the module imports
std.conv:to. Still, how to guess "to" from "i"? Finally, should the guessing
feature exclude (unqualfied) imported symbols?
