create a CODE ref from a parse tree?

[perl5ever]

It is possible to create a CODE ref that is based on the _parse tree_ of another CODE ref?

Normally we create CODE refs by specifying the source code for the subroutine.

I would like to create a perl function which takes a CODE ref as input, accesses the parse tree of the CODE ref and creates a new sub by specifying what the new sub's parse tree should be. Also, the new parse tree could contain elements from the first sub's parse tree.

Is this possible?
