good for you. :)
I lazy typing, so i usually typing the first few letters and then
using alt-q to autocomplete the selector.
And sometimes i picking a wrong method, because for me, they are not
so different..
integer is also a value.. you know :)

yeah, that's why i introduced
self cIdentifier: #sqLong

in Hydra. So, its just puts this symbol in source without any transformations.

Yeah... i could do that. But you know.. i'm not a big fan of aliased methods.

NBInterpreterProxy methodDict size 149

if i start adding aliases, it will go an go more and more. And,
usually, the more things you adding , the harder to
figure out, what you need.
