I think these are all great, but if I can be the voice of caution for
a moment...
remember that when you write code, it is for 2 interpreters:
1) the Actionscript VM
2) the person who has to go back and change stuff at a later date,
which may or may not be you...
Its often very easy to forget number 2 - so, while writing doing
things like avoiding function calls may be faster for 1) it can end up
making things a lot slower for 2)
Also, when you go through your code & optimise it, make sure you are
efficient with your efforts - you will probably find you can nail down
key performance spikes to just a few functions / algorithms... be
careful not to optimise to death, and try and measure your gains at
each step
I'm not saying code shouldnt be optimised at the expense of (human)
readability, just that sometimes it gets a little overdone...
