Module refinery.lib.scripts.au3.limits

"""
The interpreter's line limits: what one physical line of AutoIt3 source may hold. A line of 4094
characters runs and one of 4095 fails to parse, and a line ended by the continuation marker ` _`
joins the lines it spans under no combined bound, so a statement longer than one line is spelled
across continued lines rather than as a line the interpreter refuses. The numbers are probed on
the interpreter itself; the probe scripts and outputs live in `temp/au3_semantics_probe`.
