When having the following construct

attr := someList.find |UnkownType a->Bool| { return a.name == name }

Then I get the errors:

1. WARN Replace bitwise | with or method call
2. Expected end of statement: semicolon, newline, or end of block; not a

instead of something like: Unknown type UnkownType for local declaration

I think you are using an older version - because that warning is no longer in the compiler. Latest version is 1.0.51

I retried it in the 1.0.51 version and got:

Expected end of statement: semicolon, newline, or end of block; not |

The warn message is indeed gone, but I think is still should give a unknown type error or I am wrong?

The parser was designed around the fact that | could be bitwise-or or closure; of course now that we've gotten rid of bitwise-or the error handling can be cleaned up. But stuff like that is pretty low on the priority queue.
