POST::Node is the base class for all POST nodes. It's derived from class PAST::Node (see compilers/pct/src/PAST/Node.pir).

result([value]): Get/set
result([value]): Get or set the result value of this node. If the result value is set to another POST node, then that node's result is used as the result of the current node.
get_string() # vtable method: Returns the result of the current node as a string.
push_pirop(pirop [,arglist :slurpy] [,adverbs :slurpy :named]): Shortcut for creating and adding a new POST::Op node with opcode pirop and any supplied arguments or options. Returns the newly created node.
escape(str): Return str as a PIR constant string.

POST::Op

POST::Op nodes represents any PIR opcodes.

pirop([opcode]): Get/set the opcode type for this node.
