Hi,
I noticed, that I cannot throw from the lambda expression:
Error: expression expected, not throw
but have to use the longer syntax () {throw new Exception();}

void foo(void function() e){}
void main()

foo(
() => throw new Exception()
);
}

The shorter lambda syntax would be more readable in my case.
Is there a reason why it isn't allowed or should I create an
enhancement request?
Kind regards
André
Well, the shorthand syntax "=>" implies a return, but you can
only return an expression and throw is a statement.
