Certainly not common enough to warrant a two-character method on the native string type. Odds are people will use it incorrectly in an attempt to make their code look concise, not understanding that it'll retrieve a substring of .length 1 or 2, possibly consisting of a lone surrogate, based on a 16 bit index that might fall in the middle of a character; the problematic cases are fairly rare, so it's hard to notice improper use of `.at` in automated testing or in code review. -- Björn Höhrmann · mailto:[email protected] · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
