I remember Ada always having very precise and helpful error messages like this one:

literal_string.adb:5:33: warning: wrong length for array of subtype of "Standard.String" defined at line 5 literal_string.adb:5:33: warning: "Constraint_Error" will be raised at run time

then when you run the app it behaves as advertised

$ ./test

raised CONSTRAINT_ERROR : literal_string.adb:5 length check failed

There are many others and when I saw llvm improving error messages for C and C++ (which I saw happening before Rust was a thing) I always thought it was inspired by Ada and it's helpful messages like:

expected private type "<type name>" defined at ...; found type "<type name>" defined at ...

"<name>" is undefined (more references follow); possible misspelling of "<name>"

and the many others that were just there when I first tried Ada around 2008/2009.
