I think our duplicate elimination machinery needs to be smarter about removing error messages without elaborations when otherwise identical error messages with elaborations exist for the same location.
from typescript.
Found this when coming up with test cases for #57842.
The way I came up with it is to look at where we call getTypeOfExpression
, and then create a program where we call getTypeOfExpression
on an expression that produces an error that is dependent on the state of the checker, such that we end up with two different diagnostics, one when we check the expression regularly, another when we re-check the expression through a call to getTypeOfExpression
.
Note this is not unique to checking class expressions, nor to the specific error code in the example: I can likely construct other types of program that exhibit this same problem.
