It seems odd to require two syntactic elements to achieve one semantic.
And actually, after looking at A5, that's not what Larry wrote:
my $x;
/ (\S*) { let $x = .pos } \s* foo /
After this pattern, $x will be set to the ending position of
$1--but only if the pattern succeeds. If it fails, $x is
restored to undef when the closure is backtracked
I don't see any binding there, just letting.
