The result will be a tuple (optlist, optdict) but where all expression nodes have been interpreted. The result is in the form of tuples (value, pos). optlist is a list of nodes, while optdict is a DictNode (the result optdict is a dict) If type_env is set, all type nodes will be analysed and the resulting type set. Otherwise only interpretateable ExprNodes are allowed, other nodes raises errors. A CompileError will be raised if there are problems. csL|ˆkr<ˆr0| ˆ¡}|s&t|jdƒ‚||jfSt|jdƒ‚| t¡|jfS)Nz Invalid type.zType not allowed here.)Zanalyse_as_typerÚposZcompile_time_valueÚ empty_scope)ÚnodeÚixÚtype)Ú type_argsÚtype_envrrÚ interpret%s    z0interpret_compiletime_options..interpretcsg|]\}}ˆ||ƒ‘qSrr)Ú.0rÚx)rrrÚ 1sz1interpret_compiletime_options..N)Ú enumerateÚ isinstancerÚAssertionErrorZkey_value_pairsÚkeyÚvalue)ZoptlistÚoptdictrrZ new_optdictÚitemZnew_keyÚdummyr)rrrrÚinterpret_compiletime_optionss  r )Nr)Ú__doc__Z ExprNodesrZErrorsrrrr rrrrÚs
