Ruby in MacOSX 10.2 (Jaguar)

Just a small language question...
44860 [bobx@li ux a] Why does Ruby do single quotes around package names?
+ 44862 [dossy@pa op ] You can.  However, what does "require somepackage" really
+ 44863 [dblack@ca dl] It doesn't have to be single quotes -- it can be double quotes or any
+ 44864 [rich@in oe h] Because the package name represents a file name which could have spaces,
| + 44865 [djberge@qw s] Just say "No!" to Ruby modules with spaces in the file name!
| | 44870 [transami@tr ] "No!" uhh... is there some sort of standrad we should adhear to?
| + 44869 [bobx@li ux a] Er...well Python and Perl (and I think Tcl) do not seem to have this worry?
|   + 44871 [dblack@ca dl] File and/or module-loading works differently in different languages,
|   + 44874 [hal9000@hy e] worry?

+ 44868 [transami@tr ] while i think the other posts effectivly answered your question. i have
