Type of a resulting value produced by the operation represented by this definition.
Type of a resulting value produced by the operation represented by this definition.
For example, if this definition represents application of +: (Int, Int) => Int operation
then the result type is Int and resultType should return IntElement.
Dependencies of this definition from other definitions.
Dependencies of this definition from other definitions.
If definition is interpreted as an operation, then dependencies are arguments
of the operation.
If definition if compound (like Lambda of ThunkDef) then deps is equals to
free variables used in the body of the compound definition.
This array also refers to predecessors of this graph node, so it is used
to build topological ordering (execution schedule) of operations.
array of referencies to other definitions.
All data elements of this graph node to be used in structural equality.

equals where elements are used.
Default equality of definitions.
Default equality of definitions.
Two definitions are equal if they have same elements.
Override to redefine how dependencies are computed.
Override to redefine how dependencies are computed.
For example, in core implementation this is overriden in Lambda and ThunkDef using freeVars.
Computed once and saved to avoid repeated computations, which is not necessary because definitions are immutable by default.
Computed once and saved to avoid repeated computations, which is not necessary because definitions are immutable by default. If some definition require mutability, this method can be overriden accordingly.

Clone this definition transforming all symbols using t.
If new Def[A] is created, it is added to the graph with collapsing and rewriting.
Can be overriden to implement node-specific mirroring (see MethodCall).

symbol of the logical clone. If d don't contain symbols, then d.self is returned.
Unique id of the graph node assigned for each new instance using
freshId generator.
Unique id of the graph node assigned for each new instance using

Doesn't participate in equality of this Def, thus definitions with
different ids may still be structurally equal.
Used to provide global Def numbering.
