OK, so we have replace(haystack, needle, nail) which replaces _all_
occurrences of needle in haystack with nail. How would you call a
function that replaces only the _first_ occurrence of needle with nail?
Must be a distinct function, not a runtime parameter to the existing
function. This is because the function that replaces only one occurrence
only requires nail to be an input range.

If you articulate this question to yourself over and over until you
understand the *salient* problem (i.e. the real problem that sticks out)
you will answer your own question and then have no need to resort to
newsgroup answers.
If you are feeling lost, a good tactic to solve your problem is to think
about function signatures in all their D glory not forgetting, of
course, about D's innovative transitive xxx (const/immutable) constructs
to include in the specification of your function(s).
