@fabpot I think I know why so many people report this: the Symfony Debug component is still logging silenced errors by default in the dev env

[Tobion]

@stof yes that is what I said in #1848

The only "annoying" thing I noticed is, when you remove the cache and then run your app, all those non-existing template caches are reported as "silenced errors" from the symfony profiler whenever the template cache doesn't exist yet.

The backslash is not necessary before a global function.

[fabpot]

It should indeed be removed for 5.2 compat.

[fabpot]

So, the fix should be done in Symfony instead, right?

[Tobion]

@fabpot no symfony cannot do anything about it. IMO this change here is valid (apart from the CS) as it avoids alot of warning spams.

Thank you @torzech.
