#20 Block arguments not allowed in expressions

[Bryn Keller]

The parser in the current CVS version isn't allowing
block arguments when the call is the rhs of an assignment:

int foo(void->int func) = func();

void main(String[] args) {
foo() { return 1; } //works
int x = foo() { return 1; } //doesn't work
}

Only the use of a block call as statement is possible now.
This a parsing problem, I haven't found out yet how to allow a
block call as expression without requiring ; at the end of both
examples you gave.

Although it looks good on the rhs of an assignment, I'm not
sure about the usage as expression:
bar(foo(){ return 1; }. foo(){ return 5; });

Do you have an example where you to return something from
a block argument call?
Otherwise I suggest limiting it to statements only and rename
it to user defined statement.

Oh, sure:

ThreadResult<int> result = async { callSomeServer(); return 5; }

ThreadResult<int> result = waitForFirst(
async { return doSomething(); },
async { return doSomethingElse(); }
);
