Fix allows users to use a package prefix for a function on the LHS of the formula in
mold(), e.g.mold(survival::Surv(time, status) ~ age, data = survival::lung)Previously, the code checked for a colon in the terms. I updated it to use lookahead and lookbehind regular expressions to search for a colon that is neither preceded nor followed by another colon.
Thank you
