Interesting work on the regexp. I like the idea of parsing the tags
string with regexp because it is very efficient. Howevern the TWCore
defines a string method, .readBracketedList(), which is used to parse
tag string input and populate the internal tiddler data structure in
the 'store'. Thus, you would write:
var tagList = tagString.readBracketedList();
to get the actual tags that the core will use. You should do a little
comparison to make sure your regexp produces the same results.
enjoy,
