+not widely-known, sometimes misused, and so programs that use Bigstrings are
+slower than they have to be.  And even if a library got that part right and
+exposed the intrinsics properly, the compiler doesn't have any fast blits
+between Bigstrings and other string-like types.  @code{bigstringaf} provides
+these missing pieces.")
