<p>is recognized as a directive to save the current basis (i.e., environment) to
<code>&lt;file&gt;</code> (in the same format as the <code>-show-basis &lt;file&gt;</code> <a href="CompileTimeOptions">compile-time option</a>).  The <code>&lt;file&gt;</code> is interpreted relative to the source file
in which it appears.  The comment is lexed as a distinct token and is parsed as
a structure-level declaration.  [Note that treating the directive as a top-level
declaration would prohibit using it inside a functor body, which would make the
feature significantly less useful in the context of the MLton compiler sources
(with its nearly fully functorial style).]</p>
