Consistency

[Steve D via Digitalmars-d]

Python (built-in)

dict1 = {"a":1,"b":2}
tup1  = (0,1,2,3)
arr1  = [0,1,2,3]  # list type
str1  = "abcd"

print "b" in dict1    # True
print 3 in tup1       # True
print 3 in arr1       # True
print "c" in str1     # True

print tup1.index(2)   # 2
print arr1.index(2)   # 2
print str1.index("c") # 2

There is some sort of consistency of use, though they are 
different sequence/collection types.

Now try the same in D

auto dict1 = ["a":1,"b":2];
auto tup1  = tuple(0,1,2,3);
auto arr1  = [0,1,2,3];
auto str1  = "abcd";

Having some consistency involving 
sequences/arrays/strings/collections etc, which are the 
foundations of any language makes programming much easier, 
intuitive and pleasant. It shouldn't be too difficult for a super 
bare-metal language like D.
I'm honestly not knocking D (I love it), just some thoughts 
(maybe provoke some discussion?, for D3?)
