Parameters defined using function notation in neon config not available when calling getParameter

[maryo]

Version: 3.1.8

Bug Description

Parameters defined using function notation in neon config are not available both when calling $container->getParameter('php_version') or $container->getParameters().
It was working in 3.0.x, stopped working in 3.1.0, then it started to work in 3.1.5 and in 3.1.8 it stopped working again.

parameters:
    php_version: ::constant(PHP_VERSION)

(we call a different function, this is just to illustrate)

It is a bug in my opinion, at least a BC break but perhaps it is intentional?
I know a proper way is to inject the parameter inside a service but we are dealing with some legacy code.

Did it ever really work in 3.0.x? I don't think so… I tried to make it work in 3.1.5 and I made so much trouble that I don't like to remember it.

It was working at least in 3.0.2 (version we were migrating from). I just tried it.

You're right, it only worked in 3.0.2 and was reverted in 3.0.3. It's not possible to implement this feature because it causes a huge amount of problems and has minimal benefit.

In version 3.1.9, $container->getParameter('php_version') should work now.
