Oh, right, I did not think to the name::path usage, it would be weird to have both : and ::.

I like the solution to pass multiple -e options, thank you!

Hello,

The separator used between ruby executables for the benchmark/driver.rb script is ";".
This requires the argument to be quoted (at least in bash/zsh) and produce an unintuitive result if not: only the first executable is taken by the script, the second executable launches the ruby interpreter with no arguments, thus waiting on stdin, which feels like the benchmark script hangs.

I proposed to use ":", the standard path separator instead.
For compatibility, ";" could split too, but I wish to document ":" in the help.

What do you think? May I go ahead?
