RE: New "cut" operator (was: Pike 8.0 RC1)

> "cut left example" << " " == " left example"

That is useless.

what I really need is the feature of "between", just like this:

"<some thing>"<<"<">>">" == "some thing"

"<title>TITLE</title>"<<"<">>">"=="titile"
"<title>TITLE</title>"[sizeof("title")+2..]=="TITLE</title>"
"TITLE</title>">>"<"=="TITLE"
"TITLE</title>"[sizeof("TITLE")..]=="</title>"
