A popular language with a lot of documentation and user comments has a lot of instances of a common phrase? Python and Java also have pretty heavy use of the phrase, proportionally speaking (since PHP does have a massive amount of built-in functions):
I use that phrase all the time in my own comments and docs. When I use it, it's to point out something that I tend to trip up on myself, or something that is not obvious to the casual reader.
I regret nothing.
Oh PHP is why after years of not writing PHP I still have anxiety around when to use the break and continue keywords.
Tis a poor carpenter that blames the tools.
Some would claim 'tis a poorer carpenter that uses a rolling pin as a saw.
