Is it considered bad style to write: 
x^2, 2^\frac{1}{2} and 2^\sqrt{2} (without curly brackets around the superscript) 
instead of: 
x^{2}, 2^{\frac{1}{2}} and 2^{\sqrt{2}}? 
The same for subscripts.

LaTeX's peek operations are a bit of a black box for me and I'm struggle to get microtype protrusion to behave in a custom list which has a peek operation at the beginning of it.
