Re: Robert Martin on the Relevance and Future of Scripting and Dynamic Languages
Here's an interesting quote from the article:
When type-safe languages like C++, Pascal, and Ada came to the fore, we
found that whole classes of errors were eliminated by the compiler. This
safety came at a price. Every variable had to be declared before it was
used. Every usage had to be consistent with its declaration. In essence,
a kind of "dual-entry bookkeeping" was established for languages. If you
wanted to use a variable (first entry) you had to declare it (second
entry). This double checking gave the compiler vast power to detect
inconsistency and error on the part of the programmer, but at the cost of
the double entries, and of making sure that the compiler had access to
I find it amusing that he considers C++ to be type-safe. That's the first
time I've heard that. Also, apparently Mr. Martin has never heard of type
inference, which all but eliminates the problem he describes. Later, he
argues that unit testing can take the place of type checking. Perhaps so,
but if you have to write lots of unit tests to check types, you are
spending a lot of effort to do something that should be done automatically
for you (and can be, in many languages).
I think his comments more accurately summarize the last decade of
programming than the next.
