I'll pick a couple that are easy to describe. First a simple string function: "softEquals(a,b)" that compares ignoring case and leading and trailing white-space, similar to "return trim(upper(a))==trim(upper(b)). The second is to "draw" an HTML button and/or hyperlink because often the user or designer change their mind about whether it's a link, button, or icon: link(title, url, httpType=[hyperlink,submit,get,reset], dispalyType=[hyperlink,button,icon],target="",classes="",otherAttribs="",buttonImg=""); Those with "=" are optional named parameters or optional object values, depending on the language of implementation. I'll usually tune it to app or shop conventions, which can shorten the range of variations or likely defaults, and thus simplify the interface. But the implementation is mostly the same: just the interface needs trimming/tuning. Or just leave the fuller one intact for edge cases, but create short-cut versions better fitting local conventions.
