Detailed Description

Thrown when a pattern cannot be represented as a DFA.

The cause is always a zero-width assertion other than a leading \A/^ (e.g. $, \b, \B, multiline anchors). real::dfa never falls back silently — a violated contract is an error the caller handles (e.g. by keeping that rule on the Pike VM).
