This DIP fixes the problem for "body" but not for the other 
keywords. After all the problem may exist for other keywords. Was 
a new pragma considered ? For example an identifier alias.

pragma(idAlias, "body", "body_" )

would mean that any "body_" will be treated as "body" identifier. 
The translation would happen just after the grammatical parsing, 
because at this phase keywords don't matter anymore.

example:

====
module module_;

pragma(idAlias, "function", "function_" );
pragma(idAlias, "module", "module_" )

int function_()
{
     pragma(msg, __PRETTY_FUNCTION__);
     return 0;
}
====

prints "int module.function()" during compilation.
