Because apparently, while designing the Objective-C language, somebody
thought it was a world-class idea to allow any white-space between the
'@' character and the subsequent keyword. With this fix, we now
correctly parse:
@ dynamic
and:
@
selector
and:
@"foo"
"bar"
@"mooze"
(This last one is 1 single string split over multiple lines.)
Wonderful, isn't it?
What we (and Clang) do not support, but what GCC supports is something
like:
@"foo"@@ "bar" @"mooze" @@
which is equivalent to @"foobarmooze".
Also removed the (conditional) invoke_token from DeclarationAST and use
the qt_invokable_token to store the Q_INVOKABLE, and fixed the ASTMatch
code generation.
Things you mustn't do:
1) end an enum with a comma
2) #include <cxxxx> and not use std::
3) use anonymous structures
All three things are invalid C++. Anonymous structures inside
anonymous unions are allowed by GCC, but that doesn't mean it's valid.
