Paul Mansour’s APL moot, San Quirico d’Orcia, Tuscany

Morten Kromberg of Dyalog demonstrated a Unicode-happy interpreter, whipping up a chessboard as an 8×8 character array and demonstrating board='♙' yields an 8×8 boolean.

Stefano Lanzavecchia, wizard of everything that about to happen, ran from Dyalog Microsoft’s experimental Jasper object-relational interface, noting that this useful-looking tool appears restricted to dynamic languages. (Dyalog and VB can play, but C# cannot.)

Richard Smith showed his latest additions to the interpreter for his experimental Rowan array language. Rowan is written in C# and composed largely from .Net assemblies. True to creole technology principles, it is guided by what is easy for the interpreter writer to construct. Richard showed us his depth and where operators; full support for Unicode characters (his square-root function uses √ as its symbol); inline charting (the chart is displayed in the session log) and plugins for defining new functions. Way to go, Richard.

Today is a holiday; the moot resumes tomorrow.
