FGL object constructor for fast alists and arrays.
This is a product type, introduced by defflexsum in support of fgl-object.
- tag — g-map-tag
- alist — fgl-object-alist
An object constructed as (g-map tag alist) evaluates to the
evaluation of alist as a FGL object alist -- that is, a list of
pairs where the keys are concrete objects which are not evaluated
and the values are FGL objects. The g-map kind is used in
fast-alist and fgarray primitives to offer constant-time
lookups in fast alists and arrays.
- Basic constructor macro for g-map structures.
- Get the alist field from a g-map.
- Get the tag field from a g-map.
- Modifying constructor for g-map structures.
