Attempting to correct the error and move forward with the compilation
sounds good, but generally is a hopeless failure. A far better approach,
one that is half-implemented in dmd, is to replace failed types,
expressions, etc., with special error productions, and then suppress
further messages that have as operands one of those error productions.
It's analogous to using NaNs in floating point.
NaP should be its name I guess :o).
