+Syntax:
+- `[...]##+js(trusted-replace-argument, fn, argpos, argval [,condition, pattern])`
+
+Parameters:
+- required, `fn`: is the function we want to proxy through an `apply` handler.
+  This can also be a class, in which case the scriptlet will proxy
+  through `construct` handler. At the moment, `fn` must exist at the
+  time the scriptlet executes.
+- required, `argpos`: is the 0-based position of the argument we want to change
+- required, `argval`: is the value we want to have for the argument -- the value
+  is interpreted the same way the value for `set-constant` is
+  interpreted.
+
+Tokens:
+- `condition, pattern`: is a vararg which tells the scriptlet to act
+  only if `pattern` is found in the argument to overwrite.
+
+Example of usage:
+- `alliptvlinks.com##+js(trusted-replace-argument, MutationObserver, 0, noopFunc)`
