Remarks• (1) restricted to initialisation of a local variable in C and C++

• (2) a b c must be constants • (3) beware, if you give only one integer argument, it is the size! • (4) for write access: a i o put • (5) in C++, it is range-checked whereas a[i] is not. in Smalltalk, for write access: a :at i :put o • (6) see also Head • (7) list comprehension • (8) in List::Util • (9) not in standard • (10) Python >= 2.5 • (11) in C++, it is done in place • (12) in Scheme, not standard, but nearly standard • (13) the result is not guaranteed to be the same as the order in the input • (14) in Perl, in List::Util
