Problem was before that for example the input [0x000KKK] would produce a
hexadecimal and a value token (for the respective parts)
However, the more correct way is to have the whole input identified as a
value token. basicly if the whole input between "=" and a special
"end-of-assignment" token can't be identified as a string,bool,integer
whatever. it should be identified as a value token.
