# Translate SubX files with debug information.
#
# Mu's core tooling has a gap:
#   1. 'translate' can generate debug information, but syntax sugar passes
#   (sigils and calls) have no C++ versions and take several minutes to run
#   emulated.
#   2. 'ntranslate' is fast, but you get no trace for runs and zero error-checking
#   on the code emitted by sigils and calls. Which could still be buggy.
#
# This script is a hack to get the best of both worlds. We run natively what
# we must, and leverage as much debug information as possible. This arrangement
# is snappy but requires Linux just like 'ntranslate'. You also are on your
# own to mentally map desugared instructions in traces and error messages back
# to the original sources.
