Usage

{{Trim leading | <input> | <prefix> }}

Trims up to six instances of <prefix> (such as: 0 or "anti-") from the beginning of <input>. <Prefix> is set to "0" by default (for removing leading zeroes from numbers). Template will not properly work beyond the first whitespace in the input.

For backward compatibility, both the input and pattern string are trimmed of surrounding whitespace before processing begins. This means you cannot remove three instances of "the " from "the the the thing"; instead you will remove one instance of "the".
