var533 should be replaced.

Still broken (but in a different way).
Try this demo.py:

from min_artiq import *
from numpy import int32


@nac3
class Demo:
    core: KernelInvariant[Core]
    clk_sel_hw_rev: KernelInvariant[tuple[int32, int32, int32, int32]]
    clk_sel: int32

    def __init__(self):
        self.core = Core()
        self.clk_sel_hw_rev = (1, 2, 3, 4)
        self.clk_sel = 2

    @kernel
    def run(self):
        self.clk_sel = self.clk_sel_hw_rev[self.hw_rev]


if __name__ == "__main__":
    Demo().run()

RuntimeError: type error inside object launching kernel: error when getting type of field `clk_sel_hw_rev` (Incompatible types: tuple[int32, int32, int32, int32] and Exception)

Note that filename and line number are also missing from the message, in addition to the incorrect reference to Exception.

Well I guess this is due to constant folding and I forgot to add special case for that. Will fix.
