Hello,

After getting a MatchResult by calling match(source, engine): Seems that, if match has failed, calling result.hit() throws an assertion error. Then, how can I know whether match was successful? As there is always a matchResult object returned. I'm looking for a kind of success.failure flag on the matchResult.

Note: this is for single match at start of source.

I found this strange thingie in the online docs:
struct RegexMatch(Range = string);
	...
	bool chr(ref uint si, E c);
    	    Returns whether string s matches this.
???
Whether string s (which?) matches this (RegexMatch object): ???
And what are 'si' & 'c'?

You'll want to use:

if(!m.empty)

where m is your RegexMatch instance.
