My first thought was PEARL:

PEARL, or Process and experiment automation realtime language, is a computer programming language designed for multitasking and real-time programming. Being a high-level language, it is fairly cross-platform....

PEARL is not to be confused with the similarly named Perl, an entirely unrelated programming language created by Larry Wall in 1987.

But, the question is: what language programs pearls? Of course, it has to be the (Lisp-influenced, still-in-development) language Oyster.

SCNR. :-)
