What's New and Exciting in Julia
summary
Live demos show concrete claims and numbers: Julia 0.4 introduces callable objects (overloading call), docstrings, fast package loading and a Jupyter workflow; generated functions run at type-inference time to emit nested loops (no runtime overhead) and inline precomputed Chebyshev coefficients for blazing-fast boundary‑element kernels. The Julia set demo measures ~4.6s then ~0.5s after preallocation and gains roughly 2× with experimental threading; Cxx enables calling C++ (even splicing Julia into LLVM) and a gdb-style debugger is prototype but fragile.
