I would consider it as alternative. Who likes so much typing? And if you 
are alarmist, you should be afraid of possible env variable collision :)

I am not afraid of shebangs incompatibility. I hope that if there will  
be JRuby specific code, nobody will come with #!/usr/bin/ruby _jruby_ 
shebang, but will go with !#/usr/bin/jruby. Not sure why s/he would use 
such shebang anyway.
