I used to use LiveScript also as a replacement for shell/bash/batch/Makfile-like scripts. It was a good feature that the lsc binary passed on the remaining arguments to the script file like, e.g.:

lsc script.ls arg1 arg2 ...

then arg1, arg2, ... were available in script.ls with process.argv.
For LiveScript 1.3.0 this seems to be no longer the case. It thinks that arg1, ... are additional files and says:

Can't find arg1.ls

Is it a non-intended use-case using LiveScripts with arguments or is it an overlooked side-effect of maybe the introduction of optionator in lsc?
