(cons 1 2) can cause anything to happen because somebody might have redefined cons to draw circles on the screen. If some library violates common sense, don't use it. The syntax of reading a mutable variable is a perfect syntax for reading a dynamically scoped variable, or reading a thread-local variable, or reading a variable reflected from another language, or reading a lazy variable, or reading a single-assignment variable, or performing a simple transformation on another variable which used to have been exposed as a direct variable in the previous version of a library. -- __("< Marcin Kowalczyk \__/ qrczak@xxxxxxxxxx ^^ http://qrnik.knm.org.pl/~qrczak/
