The following code is created to demonstrate how swf10 compiler treats mixins. You can then decide whether you think
this is appropriate or not.

This example WORKS in swf8.
Compiling to swf10 the following error is produced:

Stray error string from external compiler:

sar.: 1 Virhe: Call to a possibly undefined method sip_and_contemplate

("Virhe" means "error" in english)
