I have some D2 source code resembling

   if (auto m = std.regexp.search(text, "x") )  {

This gives "function std.regexp.search is deprecated".  Not being 
expert at regexes in any compile-to-metal language including D, I 
hoped I could just change "regexp" to "regex" and be on my way.  
Nope, apparently the new regex isn't pin-for-pin compatible with 
the old regexp.  It doesn't have search().  The compiler gives 
"Error: undefined identifier module regex.search"

Not wanting to spend a gob of time learning regex, which I'm 
unlikely to ever use in my normal work (or abnormal work), is 
there something like a how-to cheat sheet for switching regexp 
code to regex?

maybe this might help:

import std.regex;
void main() {
	auto text = "regex";
	if (auto m = match(text, "x") )  {
	        auto c = m.captures;
	        writeln(c.pre, ":", c.post, ":", c.hit);
	}
}

For future information, posts of this nature should be posted in D.learn.
