Subject: Re: [PHP-DEV] Introducing compile time code execution to PHP preloading
From: robehickman@gmail.com (Robert Hickman)

> Once you are in a live environment you want a read-only file system, for security and auditability.  Code generation at that point is then impossible.  Moving that code gen to a preloader wouldn't help with that.

My proposal has no impact on the file system. It would modify the AST,
and thus would be entirely in RAM as opcache is also in ram. No source
files involved at all.
