I don't agree.  I find both intuitive.  The second case is a postfix 
modifier, so my brain translates it to "shorthand for while (condition) { 
EXPR }".  To change its semantics would break the symmetry of statement 
modifiers.  The first case is the same syntax and semantics as several 
languages I can recall using, although I'm too burned out at the moment to 
think what they are; but it's quite intuitive nonetheless.

Get rid of some of the other weird uses of 'do', yes...
