Least Restrictive aka All
struct IdentifierCharLookup;
bool function(dchar) isStart;
bool function(dchar) isContinue;
static pure nothrow @nogc @safe IdentifierCharLookup forTable(IdentifierTable table);
Lookup the table given the table name
pure nothrow @nogc @safe bool isAnyIdentifierCharacter(dchar c);
Convenience function for use in places where we just don't care, what the identifier ranges are, or if it is start/continue.
Returns:
is character a member of least restrictive of all.
Examples: 
assert(isAnyIdentifierCharacter('ğ'));
pure nothrow @nogc @safe bool isAnyStart(dchar c);
Convenience function for use in places where we just don't care, what the identifier ranges are.
Returns:
is character a member of restrictive Start
Examples: 
assert(isAnyStart('ğ'));
pure nothrow @nogc @safe bool isAnyContinue(dchar c);
Convenience function for use in places where we just don't care, what the identifier ranges are.
Returns:
is character a member of least restrictive Continue
Examples: 
assert(isAnyContinue('ğ'));
