Open Stack

Vitaly

Thanks for bringing this up. Actually the spec has been on review for
almost 2 weeks: https://review.openstack.org/#/c/282695/. Essentially, this
is not introducing new DSL but replacing the existing one with more
powerful extendable language which is being actively developed within
OpenStack and is already a part of other projects (Murano, Mistral), which
has much more contributors, can return not only boolean but any arbitrary
collections. So it means that we want to deprecate current Expression
language that you wrote and replace it with YAQL due to those reasons. You
are not going to extend this Expression-based language in 3 weeks up to
level of support of extensions, method overloading, return of arbitrary
collections (e.g. we also want to calculate cross-depends and requires
fields on the fly which require for it to return list of dicts) and support
of this stuff on your own, are you?
