I wouldn't want to go back to programming PHP due to its many issues[1]. I especially wouldn't want to work somewhere that spends development energy on BobX[2] to make PHP easier to work with. That means I have to use two technologies that won't give me any way to advance in the industry, and will most likely hinder me at this point.
