Thanks for the great editor.
Two minor issues that I found in the syntax highlighting, on Sublime Text 2, build 2139:
In Perl, the 'not' operator is not marked as one
In YAML, the key part ends (as much as I understand it) in colon and space.
so something like:
some:keyword: some value
now is coloring 'some' as the key, while it should mark 'some:keyword' as the key
