There really is no point in allocating a struct containing a
pointer and an int on the heap. Allocate by-value instead.
Since QList would be inefficient then, switch to QVector.
A pointer to the current token was replaced by its index.
That saves looking it up on every toPreviousToken()/
toNextToken().
This saves 816 bytes of text size on optimized AMD64 / GCC
builds, even though QVector expands to more code than QList.
