It wouldn't be a top-level namespace that would cause a conflict, but a nested one: currently the above code resolves the function name as "AcmeComponents\SplineReticulator\Utilities\Text\Text\strlen" (note the "...\Text\Text\...").

It's an interesting suggestion, but I'm not totally sold on "use the end of the current namespace" being easier to remember than "use this symbol or keyword".

return namespace\strlen("Hello World"); # current syntax, rather long and unclear
return _\strlen("Hello World"); # short, but maybe a bit cryptic
return Text\strlen("Hello World"); # variable length, relies on current context
return NS\strlen("Hello World"); # shortening of current keyword
return self\strlen("Hello World"); # maybe confusing to reuse a keyword?
return current\strlen("Hello World"); # clear, but a bit long
