No longer segfaults on DMD1.042 and 2.027 -- now generates a "forward reference" error message. This is still a regression.

Then don't just delete the keyword - assign the correct one!

I thought of doing that, but 'regression' normally applies to valid code. Regression of invalid code is a hundred times less serious. So I added the 'regression' to the description, rather than the severity.

Works for DMD 2.032 here, but not for DMD 1.047

The fact that it doesn't work on D1 isn't actually a regression. The regression
was fixed in 1.021-1.023.
It never actually worked on D1. Here's the full behaviour:
Segfault on 0.140, forward reference error 0.150-1.010, segfault 1.013-1.020,
forward reference error 1.023-present.

Segfault 2.000, forward reference 2.012-2.030, works 2.031- present.

Downgrading to normal.
