Here is an example of the losing names problem in stock R 2.2.0. Note
that below, only stock R packages are loaded, and then I manually
source in just my dtk.test.brace.names() testing function, nothing
else.
Since the list-of-lists output of dtk.test.brace.names() is very
lengthy, I've manually cut-and-pasted it into a tabular format to save
space and make inspection easier. As you can see, out of its 15 test
cases, stock R 2.2.0 fails 4 of them while the other 12 are Ok.
Too see what these simple subscripting tests actually DO, please refer
to the body of dtk.test.brace.names() from my previous emails above.
