Marek, thanks for your fantastic work on expression trees.
I see the implementation in compiler is finished so I hope it is fine to start
with bug reporting :).
It seems that when method parameters are used in expressions, like in the
following code:
using System;
using System.Linq.Expressions;
class Foo
{
public void Goo (bool hoo)
{
bool _hoo = hoo;
Expression<Predicate<Foo>> x = obj => hoo; // doesn't work
Expression<Predicate<Foo>> y = obj => _hoo; // works
}
}
The compiler crashes with:
Unhandled Exception: Mono.CSharp.InternalErrorException: foo.cs(5,7): Foo --->
System.InvalidOperationException: Method 'Foo.Goo' does not have a method body.
