Fixed an issue where invocations like .[a, .., z] <- letters would
also create a binding called ... (#4)
dotty now requires all arguments within a .[] invocation to be
either named or unnamed -- that is, .[a = a, b] <- c(a = "a", b = "b")
are now disallowed. This may be relaxed in a future release. (#3)
dotty::dotify() is now exported for use by R packages which would
like to use dotty internally. (#1)
