Jon Siwek	8b46bbb1c0	Change substring index notation to use a colon (addresses #422). ... String slice notation is written as `s[1:2]` instead of `s[1, 2]` because the later is ambiguous with composite index types.	2013-01-07 13:29:05 -06:00
Jon Siwek	55c515d50a	Add array-style index accessor for strings. Addresses #422. ... The index expression can take up to two indices for the start and end index of the substring to return (e.g. "mystring[1,3]"). Negative indices are allowed, with -1 representing the last character in the string. The indexing is not cyclic -- if the starting index is >= the length of the string an empty string is returned, and if the ending index is >= the length of the string then it's interpreted as the last index of the string. Assigning to substrings accessed like this isn't allowed.	2012-12-20 17:13:06 -06:00
