Parsing Issue w/ && Operator

I'm not sure why this is at the moment, but:

matches Foo '([A-Z])\w+' && echo true

Gives the following output:

ion: syntax error: '(' at position 13 is out of place

But this:

matches Foo '([A-Z])\w+'; echo true

Gives:

true

I've also noticed that this:

matches Foo '[A-Z]\w+' && echo true

Gives no output, but this does:

matches Foo '[A-Z]\w+'; echo true

Likely the same issue, and likely in the StatementSplitter logic.
