 	- wrap: Force a line wrap at the given width. `wrap 80 "imagine a longer string"`
 	- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, "<br>", $html`
 	- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)
