Re: English Idiom in Unix: Directory Recursively

the iterative code. To my mind that isn't really an iterative algorithm anymore if it ends up simulating the call stack. Tree walks are the canonical example of what can't be done in an iterative fashion without the addition of an explicitly managed stack -- Thomas A. Russ, US

nless. Interestingly, that also allows one to treat percent (%) as a dimensionless unit with a conversion factor of 1/100. -- Thomas A. Russ, USC/Information Sciences Institute -- http://mail.python.org/mailman/listinfo/python-list

Re: Lisp-likeness

you can use simultaneously? The lisp snippet creates new functions each time the addn function is called, so one can interleave calls to the individual functions. -- Thomas A. Russ, USC/Information Sciences Institute -- http://mail.python.org/mailman/listinfo/python-list
