1) builtin methods are living in a class namespace e.g.
Float."cos" ParrotIO."open" # unimplemented
2) these methods can be called in various ways:
Px = cos Py # opcode syntax cos Px, Py # same Px = "cos"(Py) # function call Px = Py."cos"() # method call cl = getclass Float Px = cl."cos"(y) # class method m = getattribute cl, "cos" Px = m(y) # bound class method m = getattribute y, "cos" Px = m() # bound object method
3) the function PMC lookup is now done in two different ways:
- if the function name is in the current namespace:
set_p_pc # get Sub PMC from constant table
- else
find_name Px, Sy
find the name Sy in lexicals, globals, builtins in that order.
This is used for PIR function calls like:
foo()
Related changes:
- PyNCI has now it's own invoke because NCI.invoke is shifting arguments down for class methods. (Py* methods are passing the object in P5)
- sort tests didn't a proper find_global
- 1 dumper test used the wrong namespace
- invokecc clears now REG_PMC(2) so that a Sub PMC can detect, if it's called as a method or not
Comments welcome, leo
