Bug
Description
The compiler generated extension "BeginInvoke" is ambiguous when generated for methods that differ only by return type.
The original testcase follows; a more descriptive testcase is attached as BOO-831.boo.
—
Adding the line "Next tune..." results in BCE0004 in the BeginInvoke line. But problem is really that TimeRemaining should be TimeRemaining()
partial class MainForm:
...
def ShowValues ():
ValuesEdit.Text = \
...
"Tune value: " + Tune.CurrentTuneValue ().ToString () + "\n" + \
"Next tune: " + Tune.TimeRemaining.ToString () + "\n" + \
""
...
private def RunBtnCheckedChanged(sender as object, e as
System.EventArgs):
...
_RunResult = RunThread.BeginInvoke()
...
def RunThread():
Running = true
...
static class Tune:
...
static def TimeRemaining ():
return NextTuneTime - DateTime.Now

Preliminary research shows that Mono has no problem with overloads of BeginInvoke, but MS.NET still does.
I'm attaching a macro that implements simple asynchronous calls, thus:
# invoke Foo asynchronously with a callback
async Foo(parameters...):
print "Called back"
This isn't exactly what's needed to replace the BeginInvoke overloads, but if we're going to implement MetaMethods as described in the links Cedric posted, the code will probably be very similar.
Cedric - it's all yours

Attached a compact testcase that explains the error.
