[r6rs-discuss] [Formal] "#! /usr/bin/env" is not "portable." It's Unix-specific.

I am posting this as an individual member of the Scheme
community.  I am not speaking for the R6RS editors, and
this message should not be confused with the editors'
eventual formal response.

Perhaps we can devise an R6RS that only one implementor
will want to implement.

Seriously, I don't mind if a program that runs in ten
minutes on my machine takes an hour and a half on Mike's
identical machine.  I would object, however, to anything
that would make the program run for an hour and half on
my machine.
