Re: I-D: The Java LDAP Application Program Interface

[David L. <dav...@cs...>]

more on the mapping of the java api to python (which it seems is a good thing)

what I forgot to say in my previous message was that I wanted to encourage
you (readers of this list) to attempt to convert some of the I-D examples into
python as an exercise that might reveal what Java idioms have been used that
make it incompatible (or uncomfortable to use) with Python.

Java's Iterator and Python's 'for' construct are good examples where they are
interchangable in many situations - but not all. only by attempting some
expressions do you find out how clumsy/elegant/robust/error-prone they are.

remember, by adding a library we are effectively extending a language.
With a little work, future expressions in this language extension will
be natural and effortless to its users.
