Instantiations of parameterized routines can be used as expressions. The form is
<idn> <actual_parms>The idn must denote a routine definition (9.1,10.2). The actual parameters actual_parms are the parameters being supplied and legality checking is the same as for type instantiation (3.2.2). The value of such an expression is a routine object.
The type of the resulting routine is derived from the parameterized routine interface (9.3) by replacing each occurrence of a formal parameter with the corresponding actual. Thus for
p[T] (x: T) returns (T) signals (E) where T has lt(T ) returns (bool)the instantiation
p[int]is legal and has type
proc (int) returns (int) signals (E)Instantiation of parameterized methods is discussed in Section 7.10.
