    1 The attached script checks for errors in which a variable declared in a {{{for}}} loop is captured by a lambda or function definition. If the lambda/function is executed after the loop iteration in which it was created, it will refer to some later value of the variable, which is usually not what was intended.

    33~~The script currently produces false positives if a variable is declared and used in the same lambda/function within a for loop (i.e. it is not captured). I don't intend to fix that until after the Tahoe summit in November, probably.~~ However, it produces relatively few false positives already, and found some genuine bugs (see #1556).
