What is Expressiveness in a Computer Language

Read this article... think it's v interesting if you're into linguistics, be it of machines or men.

In languages human or computer, there's a notion of expressiveness.

English for example, is very expressive in manifestation, witness all
the poetry and implications and allusions and connotations and dictions. There are a myriad ways to say one thing, fuzzy and warm and all. But when we look at what things it can say, its power of expression with respect to meaning, or its efficiency or precision, we find natural languages incapable.

These can be seen thru several means. A sure way is thru logic,
linguistics, and or what's called Philosophy of Languages. One can also
glean directly the incapacity and inadequacy of natural languages by
studying the artificial language lojban, where one realizes, not only
are natural languages incapable in precision and lacking in efficiency,
but simply a huge number of things are near impossible to express thru
them.

One thing commonly misunderstood in computing industry is the notion of
expressiveness. If a language has a vocabulary of (smile, laugh, grin,
giggle, chuckle, guffaw, cackle), then that language will not be as
expressive, as a language with just (severe, slight, laugh, cry). The
former is “expressive” in terms of nuance, where the latter is
expressive with respect to meaning.

Similarly, in computer languages, expressiveness is significant with
respect to semantics, not syntactical variation...[continue]
