The INTERCAL language reference manual supplies these pronunciations (and interpretations) of the ASCII characters used in the language. Since these names are particularly evocative and convenient, I reproduce the table here, slightly reformatted.

The phrases "identify ..." indicate that these are sigils. Interestingly, Perl stole from INTERCAL the usage of a prefixed sigil to mark types of some language constructs.
