Some PHP functions used in {do} are namespace\ prefixed in latte cache file, resulting in Error

[forgie1]

Version: 3.0.4

Bug Description

For example PHP function unset() can not be called in {do} macro:

Error Call to undefined function unset(), did you mean reset()?

In Latte Cache file it is prefixed : namespace\unset($abc).

Steps To Reproduce

{do unset($abc)}

Expected Behavior

$abc is unset.

I'll find out why this is happening, however to use unset you need to install RawPhpExtension.
