Was there a reason the string class was implemented with str[i] 
returning the code of position i in str?  The reason I ask this is that 
in other languages str[i] returns the string starting at position i. 
For example C uses t = strcpy(str[i]) and Business Basic uses S$=T$(I) 
to copy a string from position i.
I can see no way to do this in Ruby other than using something like: t = 
str[i,9999].  It seemed strange that copying ranges of strings uses the 
same format as C (t =strncpy(str[i],n)) but not when copying the remainder.
