If you have a proposal to improve the TCL language then the TIP mechanism is the approach to take.

However, IMHO, namespace commands, especially ones that create namespaces should be done with the [namespace] command. It would be helpful to be able to grep for "namespace" to find all the relevant commands. Having an exception, where some other command also can create a namespace seems quite odd to me and could cause some confusion for someone other than the author trying to understand or maintain a TCL program.

As to performance, I doubt that a command very likely done but once in a program will cause any issues in that regard.

That said, I wouldn't mind seeing a command:

namespace create name ?script?

which seems to me to be an oversight. When I first looked into namespaces, I found it odd that they were created with the eval option. At minimum, this would be a useful self documenting addition.
