Detailed Description

template<class MonoidValue, class SemiringEltValue>
class vcsn::algebra::KRatExpToken< MonoidValue, SemiringEltValue >

Schrödinger's token for rational expression lexing.

Tokens are ambiguous. For example, '1' could be interpreted both as a weight and as the empty word. So we assume that each possible token is in fact part of the *same* token. This is the Schrödinger's token this class represents.
