This release builds with gdc 0.15, fixes a reference scope bug in buffer variables, provides a way of appending text from the "?" mechanism to buffer variables, implements and demonstrates additional builtins for conversion, adds a new example of lexical analysis combining "?" with buffer variables, and updates the documentation.

It's worth looking at the lexical experiments example to see how the (Variable) mechanism for appending to a variable that is used as an output buffer now interacts with the "?" mechanism.
