These days, sure. E.g., recognizers allow you to distinguish between
1/11/2016 and 11/1/2016, and let the latter produce the same result as
11/01/2016.
However, recognizers are a recent addition, and not yet present in any
released version of Gforth. So they are not the reason why nobody has
asked for this feature. My guess is that it is superficially cute,
but lacking in practice. Usage examples given were:
Dates: There you have the problem of significant separator placement
indicated above. Ok, tell the user to always use two-digit month and
day names, but without input checking, this would be too brittle for
my taste.
Telephone numbers: Here separators can be placed anywhere (most of the
time, see below), but SwiftForth does not accept all characters that
customarily appear in telephone numbers, e.g.:
(+43)-1-58801-18515
Also, leading zeros and the + here are significant. So the feature
does not quite cut it for this example, either.
