The question began when I was investigating an equivalent to pyc.py in
IronRuby. ir.exe has an experimental option called -save (which doesn't
currently work) -- instead of some kind of irc.rb -- but it shows that the
lack of a consistent approach to compiling source code files into an
Assembly causes confusion for language implementers and, ultimately, users.

The approach in ir.exe is inherently broken because the base DLR
OptionsParser parses a single file input argument (called FileName), whereas
compiling usually (not always) needs to compile more than one source file
into the output file.

As you mention, the DLR methods like ScriptCode.SaveToAssembly already do
the bulk of the work, so why not work into this into the DLR?
