It is now possible declare foreign handler types:

foreign handler type MyCallback(in pContext as optional pointer, in pValue as any) as CBool

When used in the context of a foreign handler definition, a foreign handler type will cause automatic bridging of the LCB handler to a C function pointer which can be called directly by the native code.

The function pointers created in this fashion have lifetime equivalent to that of the calling context. In particular, for widgets they will last as long as the widget does, for all other module types they will last as long as the module is loaded.
