Feature Request: inline pseudo-instruction

Hi everybody, I have an application where a small file is included at multiple places. So far so good. The problem is that this include consists in a small piece of code which is inside a multi-level loop. The include is done about an average of 100.000 times . When I manually replace the include with the code which is inside, the performance boost is about a 50-100 factor.. (with opcache enabled, it is far worst without opcache). The problem is that if I make a change within the code, I do have to not forget to make changes a dozen of places... Could it be possible to add a directive such as : inline < filename > That includes the file inline within the compiled pseudo code (at compile time) ... (it does not have a big importance for me that the target pseudo-code sets the line number of all inlined instructions to the line number of the inline directive) Am I the only people needing this feature ? Best regards, Pascal KISSIAN
