Catch ex as exception when IL = WTF

Roy's post about the when statement in VB got me thinking about how that would be implemented in IL.  I'm not an IL expert by any means, but that doesn't look regulation to me.  I can follow it, but it looks like spaghetti code to me.  I'd stick with an if statement or something.

.try IL_0002 to IL_0008 filter IL_0035 handler IL_0053 to IL_0062
