[MacRuby-devel] objective-c runtime

[Laurent Sansonetti]

Hi,

Good catch, the Method structure is likely clashing with the Ruby Method class :) I'm not sure if we should try to make it work, as it's surely an edge case. Maybe #load_bridge_support_file should accept a Module object where the constants should be defined, as a second, optional, argument?

As for calling the runtime from MacRuby, I think that most runtime functions are already used in MacRuby somehow and exposed through the Ruby API. 

For example, #methods(true, true) calls class_copyMethodList().
