How to write beveled fractions like ${}^a/_b$?

In contrast to $\frac{a}{b}$ and $a/b$ (see this question).

There is the undocumented option Beveled in the FractionBox

FractionBox[a, b, Beveled -> True] // DisplayForm

One can use Style and FractionBoxOptions to set Beveled:

Plot[Sin[x], {x, -2 Pi, 2 Pi},
  Ticks -> {Pi Range[-2, 2, 1/2], Automatic},
  BaseStyle -> {FractionBoxOptions -> {Beveled -> True}}]

It doesn't look too good here, though:

This looks ok,

Style[3 Pi/2, FractionBoxOptions -> {Beveled -> True}]

but not in the "Label" style,

Style[3 Pi/2, FractionBoxOptions -> {Beveled -> True}, "Label"]

Thanks for the detailed example! Fractions in the "Label" style is looks ok for me (Mathematica 9.0.1, Linux): – ybeltukov Oct 8 '13 at 14:34
@ybeltukov It seems to be better on Linux than on my Mac. – Michael E2 Oct 8 '13 at 14:40
