Expression language: Whitespace aware parser required in rules language for assertion separation

[pieterbos]

The current rules language requires a whitespace aware parser in two places. This issue is about the separation between assertions. Say you have the following rules syntax:

/path/to/value/one = /path/to/value/two 
/path/to/value/three = /path/to/value/four

Without a whitespace-aware parser, it's impossible to detect the beginning and end of the second path reference: is it /path/to/value/two and /path/to/value/three? or /path and /path/to/value/two/path/to/value/three? Or /path/to/value /two/path/to/value/three

I would propose a ';' as separation between assertions. This solves this problem and it quite easy to type. Also it allows you to write statements over multiple lines. But more solutions than this one are possible.
