L is a programming language invented by Oscar Bonilla, Tim Daly, Jr., and Larry McVoy from COMPANY: BitMover. L is a compiled-to-byte-code language compiling to Tcl byte codes and thus leveraging the entire Tcl runtime.
L is designed to peacefully coexist with Tcl. L functions may call Tcl procs and vice versa. They may also coexist in the same source file.
L is a static weakly typed language with int, float, string, struct, array, and hash as first-class objects. The L syntax is reminiscent of C with a tiny bit of C++ thrown in.
