stripped

Returns a slice of the passed string with any preceding or trailing passed characters sliced off. Implementation template capable of handling both individual characters and strings of tokens to strip.

It merely calls both strippedLeft and strippedRight. As such it duplicates std.string.strip, which we can no longer trust not to assert on unexpected input.
