I am not sure what the rules for the request should be, but

p "(1..2)".to_range     # 0..2 original request
p "1.2 - 7.2 + 3".to_range   # 1..0
p '"a".."c"'.to_range   # 0..0

all produce things I wouldn't want.

I see Justin Collins got in the eval suggestion before I
finished looking at it.  I note that

eval("1.....7")

causes a syntax mistake.  Is there a way to handle syntax
problems parallel to execution errors?
