 Note that ACT is very strict about type-checking; so, for example, ''driver<4>'' and ''driver<4,true>'' are //not// treated as the same type even though the default parameter value for the second template parameter is ''true''.
+==== Grouping parameters ====
+Parameters can be combined into [[language:types2:data#parameter_structures|parameter structures]], to organize a large number of parameters and treat them as a group. Parameter structures can also be used as a template parameter types.

+In the linked example, ''fixpoint<a,b>'' corresponds to a fixed-point number with ''a'' integer bits and ''b'' fractional bits following the standard Q(a,b) format.
