Summary: Whole Program Optimiser
Key: GROOVY-9731
URL: https://issues.apache.org/jira/browse/GROOVY-9731
Project: Groovy
Issue Type: Improvement
Reporter: Suminda Dharmasena
Can a whole program optimiser be added which:
* specialises primitives - e.g. [https://github.com/dotty-linker/dotty]
* rewriting system to implement library-specific optimisation - e.g.
[https://github.com/dotty-linker/dotty]
* converts arrays of objects to primitive arrays in a column-oriented format
like Apache Arrow to accelerate arrays.
* Use unsafe array indexing to speed up array access- e.g.
[https://blog.bramp.net/post/2015/08/26/unsafe-part-2-using-sun.misc.unsafe-to-create-a-contiguous-array-of-objects/,]

* Better map, list for literals - e.g.
