Just my two cents:

1) The major problem here is that C has no string representation at all. I
don't exactly know any portable way to do string manipulations in C.

2) I feel the major issue here is capturin brackets. a&(b) -> a(b)|(b)a but
those capturing brackets should be the same group. Thus it surely needs parser
modifications. And choosing & sign for this operator is somewhat strange since
it usually means 'and'. Btw how would you define /a&b&c/ and /a&(b&c)/ ?
