Thanks Jim,
I'm more trying to understand the underlying type semantics with delegates.
How would I do something like this:
>>> a = System::Array[System::Delegate].new(5)
=> [nil, nil, nil, nil, nil]
>>> a[0] = lambda {|x| puts x }
mscorlib:0:in `InternalSetValue': Object cannot be stored in an array of
this type. (System::InvalidCastException)
from mscorlib:0:in `SetValue'
from mscorlib:0:in `System.Collections.IList.set_Item'
from :0:in `[]='
from :0
>>> l = lambda {|x| puts x }
=> #<Proc:0x0000084@(unknown):1>
>>> a[0] = &l
unknown: syntax error, unexpected AMPERSAND
(Microsoft::Scripting::SyntaxErrorException)
Thanks,
Martin
