270	'^~' 'location' 'prefix' fails with named captures & '^~*' usage also fails totally	j vp		"1.) one should expect that case sensitivity plays no role when using the ""stop searching"" notation (a '`^`') for 'location' regex's, but the '`^`~' prefix works and '`^`~*' does not.

2.) one can get the '`^`~' syntax verified at start-up with named captures as per this example:
	location	`^`~	`^`(?<epre>.+)?/error(?<efile>\/.+)$	{}
but as soon as you add usage of the named captures, the verification fails at that point (not at the regex itself). however, this does not happen 100% of the time! occasionally, if you have just one (1) named capture; the verification step completes w/o error.

this was discovered when the previous example was working with only the 'epre' capture and began to fail when the 'efile' was added. thereafter, removing the second capture would sometimes verify and sometimes not. seemingly, the problem is positional in its intermittency; since removing the first capture and leaving the second one never verified.

it seems the ""stop searching"" notation is not well-known/-documented and this may be why this problem is not widely reported.
