We already see an evolution happening in the way Filters replaced the LookUp() formula (not to confuse with the Lookup function of a column) and in a next step we see more and more people using Contains() instead of the is equal symbol ‘ = ’. Instead of writing: Name = “Christiaan”, the preferred way today is: Name.Contains(”Christiaan”). The latter opens a world of opportunities you do not easily see in the first version of the Coda Formula Language. There are other examples like using chaining instead of the ToText() to force a comparison of equals. These examples show the evolution of the CFL and we only see the beginning.
