Suminda Dharmasena commented on BEAM-265:
-----------------------------------------

I am not saying not to support language dependent function but have a mechanism 
to specify function in a language independent way.

> Dynamic Pipeline, Transformation, etc. / DAG Changes DSL | Full Specification 
> Language Independence, Transo

> There should conditional / dynamic changes to pipelines and DAGs. The Beam 
> specification should ideally be:
>  - fully language neutral to support many languages
>  - should be specified statically so code generation can work. E.g. pipeline 
> specified in Java but run as native. In this case the conversion would be 
> like that GWT does with Java.
> In addition the transformation code though expressed in a given language 
> should be transformable into an language independent form.
