+<title>Conditional "use" statements</title>
+Some people are tempted to do something like that:
+However <pdoc_f f="use">use</pdoc_f> is a compile-time statement and will
+always be performed if detected. As a result one should instead use
+<pdoc_f f="require">require</pdoc_f> or, less-preferably, string-eval
+with the call to use within.
