--- Comment #1 from Jacques-Henri Jourdan <jacques-henri.jourdan at inria dot Fr> ---
My explanation of the problem is that the parser has to do a lookahead to make
sure that there is no "else" associated to the selection statement. However,
this lookahead is done in the wrong context, which make T look like a variable
(while it is actually a type name).
