There were a lot of really complicated things added in 2.10, so now I wouldn't be so certain. I used 2.9, and personally I found it very easy to read and write, most of the time.

What complicated things were aded 2.10 that do not require the -experimental flag to be set? Experimental means what the name implies. An experimental feature can disappear or change in the next release. It's there to experiment with but generally not to use in production code.
