I think we can assume that the AST closely matches the core 
language since we assume «D3». So I think we also can assume the 
ability to at least construct AST trees programatically (maybe 
also inspect, but I don't fully understand the implications in 
relation to ```static if``` etc).

This would allow for more elegant and less error-prone creation 
of facades and interfacing-types (e.g. automatic construction of 
intelligent smart pointers, APIs for transport over network etc.)
