In the case of y1, the difference between a function and a variable will be noticed by the compiler. It will complain anyway. Without actually looking things up, I suspect the same will apply to index. Hmm, just noticed that with -Wshadow, ALL of EFL was failing to compile. So I've removed it again. BTW, I just looked up what Bessel functions are. I really doubt they will ever be used anywhere at all in edje. Well, unless raster wants to get really fancy with his new sound stuff and add funky audio filters. I also now know what half integers are, and why it's an important mathematical concept. Ah the things they don't teach you in high school maths. -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
