Re: [TCLCORE] Agressive shimmering

[Porter, D. <don...@ni...>]

You're going to have to reveal whatever secrets you're not telling, because
my copy of Tcl 8.4.14 shows:

int
Tcl_GetCharLength(objPtr)
    Tcl_Obj *objPtr;    /* The String object to get the num chars of. */
{
    String *stringPtr;
   
    SetStringFromAny(NULL, objPtr);


Every [string length $x] will shimmer $x to the "string" Tcl_ObjType.

That's not my experience, comparing 8.4.14 vs 8.5.8.
And practically speaking we deal with simple ascii 99.999% of the time, iso8859-1 technically.  Also, most of the [string length] operations only care about !=0 tests.
