[texhax] overstruck gamma

[Joel Salomon]

OK, I've found something that sort of looks right.  Some newbie
comments included:

\newcommand\gammabar{{\gamma\mathchoice	% gammabar
	{\makebox[-0.05ex][r]{\vrule height0.50ex width.40em depth-0.43ex}}%
displaystyle
	{\makebox[-0.05ex][r]{\vrule height0.50ex width.40em depth-0.43ex}}% textstyle
	{\makebox[-0.01ex][r]{\vrule height0.35ex width.28em depth-0.30ex}}%
scriptstyle
	{\makebox[-0.00ex][r]{\vrule height0.25ex width.20em depth-0.22ex}}%
scriptscriptstyle
	}%
}

How would mathpalette make this easier?
