I've just made the refact using typeof(null) and gained 78 SLOC
The pattern was:
void issueError();
and then in the code, in a dozen a function returning different
classes types
if (...) {
issueError();
return null;
}
now this becomes:
typeof(null) issueError();
if (...)
return issueError();
I wish I knew that trick before. I prefer typeof(null) in case I
would translate to another language. I tend to type the static
type when I know it anyway.
