[ITK-users] Suggestions about Python wrapping of cpp project

[vincent ngai]

I'm no expert, but previously when I worked on projects where we exposed
almost all core functionalities via scripts, it seemed like a good
initially, but what really happened is a shifting of complexities. Rather
than have the complexity on the C++/Compiled codebase side shifted over to
the scripts, in situation where you need to be able to change functionality
without recompiling the source, or even have access to the source, scripts
are the way to go. But shifting complexities to the runtime/script side has
its own issues, I'm happy with the C/C++ toolchain maturity, Visual C++,
GCC, GDB etc, you have very comprehensive debugging and editor facilities
available for C++, but on the script side you have far less tools, and
debugging may be a hassle.

Also for scripts that are scoped by whitespace/tabs and are not strictly
typed, we found that scripts exceeding 1/2 pages in length tend to be less
maintainable, and the chances of nuking a whitespace or overwriting a
variable gets higher.

Just my 2 cents
