20 Templates in D use a different syntax than in C: whereas in C template parameters are wrapped in angular brackets (Template param1, param2 D uses an exclamation sign and parentheses: Template!(param1, param2).
It is a nice approach for creating generic heap-based containers.
Musser, David.; Stepanov, Alexander., Generic Programming 5 Generic programming paradigm is an approach to software decomposition whereby fundamental requirements on types are abstracted from across concrete examples of algorithms and data structures and formalized as concepts, analogously to the abstraction of algebraic theories.The flatten function in PolyP is here provided as an example: flatten : Regular d d a - a flatten cata fl polytypic fl : f a a - a case f of gh - either fl fl g*h - (x,y) - fl.Length; i) 17 if (mpareTo(lowest) 0) 18 listi lowest; 19 20 The MakeAtLeast method allows operation on arrays, with elements of generic type.This avoids the C parsing difficulties due to ambiguity with comparison operators.Several iterator concepts are specified in the STL, each a refinement of more restrictive concepts.g.The generic constraint ensures that elements of a sorted_list can in fact be sorted.A pair of iterators pointing to the beginning and end of the subsequence or range to process.Templates in C may also be used for template metaprogramming, which is a way of pre-evaluating some of the code at compile-time rather than run-time.As further consequences: there is no possibility of code bloat (code bloat is common in C and requires special care, as explained below).

Suitable for a vector).
It has few words that expose the compiler behaviour and therefore naturally offers genericity capacities that, however, are not referred to as such in most Forth texts.
