#name ⇒ String

For documentation purposes symbol table context needs a name (For procedures, and macros name is ovbious. For a set expression we define name set a string “Set+<generator set>”

Returns:

  • (String) —

    name identifying context in symbol table

#symbol_definitions ⇒ Hash:Array

Some variables in ‘set_expression’ (most likely) refer to variable defined in set constructor generate. Return name of this variables.

Returns:

  • (Hash:Array) —

    with :node_type,:value, :tree -properties
