Single ASsignment Language
<language> (SASL) A functional programming language designed by Professor David Turner in 1976 whilst at St. Andrews University.
SASL is a derivative of ISWIM with infinite data structures.
It is fully lazy but weakly typed.
It was designed for teaching functional programming, with very simple syntax.
def fac n = n = 0 -> 1 ; n x fac(n-1)
A version of the expert system EMYCIN has been written in SASL.
SASL was originally known as "Saint Andrews Static Language". Not to be confused with SISAL.
