Hi there,

is the new object creation strategy in xtend2 already available in the
nightlies? Sven mentioned a keyword 'instancefactory' (see below) but I
did not find it in the nightly v.2.2. Is there or will there be
something similar?

Cheers,
Hauke

Hi Hauke,

we implemented another approach. See recent blog entries about the
builder syntax.

Regards,
Sebastian
