Hello.

Great idea.

At the moment, PHP has several static analyzers.
But what would be really great is the ability to extend and combine
them =E2=80=94 for example, having a separate module that determines the da=
ta
type of a variable. That component would be invaluable and could be
reused for various purposes, not just within LSP.

In JavaScript, the equivalent of such a =E2=80=9Cring of power=E2=80=9D was=
 the Babel
project, which allowed manipulating the AST and writing custom
plugins. I think PHP could benefit greatly if such a tool were built
as a standard for AST analysis, allowing small plugins to be created
for it with minimal effort.
