+### Notes
+
+* (1) PyPy 5.7 appears to be incompatible with Numpy builds for Python 3.5. I didn't manage to find any information on Numpy support in earlier (pre Python 3.8) version of PyPy.
+* (2) IronPython is incompatible with Numpy.
+* (3) Being a WASM application, Pyodide is bound to browser runtime, which does not allow to measure script execution time easily.
