Tcl doesn't have fewer features, it packs in a lot, probably because of its maturity, to a similar level as other mature scripting languages (OO, coroutines, event loop, slave interps, etc, etc). But it's poor when you want something to run quick, or if you want to carefully manage memory because you have a lot of data. Also there is no typing, and for large code bases that is detrimental. But by using two languages you can get the best of both worlds. But then you need to program competently in two languages, and that takes a surprising amount of experience, and the hand saw and hammer analogy isn't accurate in this case.
