The problem is when serializing tokens to a CSS string. Some tokens can 
not be written next to each other because they would not have the same 
meaning when tokenized again.

The example is 1/**/.1
If the tokenizer ignores comments, it will give two NUMBER tokens. 
Serializing them naively gives 1.1, which is now a single token with a 
different meaning.
