Comment Comment by luuuzeta The author defines a _sigil_ as follows:* a non-alphabetic character* that is at the start of a word* that communicates meta-information about the word.He gives the example of `echo $USER`, where `$` is a single that communicates that `USER` is a variable, presumably with some contents. Thus, I'd wager `$` is a sigil in `$foo`. parent luuuzeta 3 years ago
