Namespaces
namespace	real
	REAL's public API: real::regex, real::static_regex, real::flags and the match/iterator types built on them.
namespace	real::detail
	DFA construction internals: subset construction over a flattened NFA. Not a stable API.

Variables
constexpr std::size_t	real::detail::default_max_program_size {262144}
	max_program_size's default.
constexpr std::int32_t	real::detail::default_max_repeat_count {1000}
	max_repeat_count's default.
constexpr std::int32_t	real::detail::default_max_group_count {32766}
	max_group_count's default.
constexpr std::int32_t	real::detail::default_max_nesting_depth {200}
	max_nesting_depth's default.
constexpr std::int32_t	real::detail::default_max_lookaround_length {255}
	max_lookaround_length's default.
constexpr std::size_t	real::detail::default_max_dfa_states {65536}
	max_dfa_states's default.
constexpr std::size_t	real::detail::max_program_size {default_max_program_size}
	Maximum number of NFA instructions in a compiled program — 256 Ki by default (REAL_MAX_PROGRAM_SIZE).
constexpr std::string_view	real::detail::program_too_large {"program too large"}
	The cause a program past max_program_size is rejected with (real::regex_error::cause).
constexpr std::int32_t	real::detail::max_repeat_count {default_max_repeat_count}
	Per-quantifier bounded-repeat cap, enforced at parse time (REAL_MAX_REPEAT_COUNT).
constexpr std::int32_t	real::detail::max_group_count {default_max_group_count}
	Maximum capture groups; bounds slot_count = 2 * (groups + 1) (REAL_MAX_GROUP_COUNT).
constexpr std::int32_t	real::detail::max_nesting_depth {default_max_nesting_depth}
	Maximum parser recursion depth; prevents stack overflow on deep nesting (REAL_MAX_NESTING_DEPTH).
constexpr std::int32_t	real::detail::max_lookaround_length {default_max_lookaround_length}
	Maximum bytes a bounded lookaround sub-pattern may consume (its L_max); bounding it keeps per-position evaluation linear (REAL_MAX_LOOKAROUND_LENGTH).
constexpr std::size_t	real::detail::max_dfa_states {default_max_dfa_states}
	Maximum DFA states (opt-in real::dfa; REAL_MAX_DFA_STATES).
