C++ introduced it a while ago (C++11), and D has had it from the

[I'm] surprised Basic needs it. The last time I looked, $A was a string,
%B an integer, and C a number. Type inference wasn't hard!
Back in the day this was certainly true. Most modern Basic dialects are
more C-like in their declarations.
(And trying Freebasic, it insists on variables being declared anyway.
It's rather like C but with Basic syntax.)
FB could be considered C-like with a Basic syntax, yes, but with dynamic
strings and dynamic arrays. This idea of being c-like makes FB kind of
interesting but uninteresting at the same time. Kind of hard to come up
with a good reason to use it for something, especially when a dynamic
language like Python, combined with C, is so flexible.
I suppose one reason is that it is easy to get up to speed with little
effort, with something that is friendlier and a little higher level than
C. Actually, I was pleasantly surprised at its capabilities.
(Example, calling fib(40) on the example below took 90 seconds on Python
3.4, 11 seconds with PyPy, but only 1.8 seconds running the equivalent
with FreeBasic:
def fib(n):
if n<2:
return n
else:
return fib(n-2)+fib(n-1)
There are doubtless all sorts of ways of getting that sort of speed in
Python, but it's something extra to be researched and to do and could
require using an auxiliary language. Maybe there are too many possible
ways which is another problem.)
