Expression 2: function predefinition is broken

[stepa2]

Following code does not compile.

@strict
function b() { error("undef") }

function a() { b() }
function b() { a() }

No workarounds that keep type checking of argument and return value.

It shouldn't compile. Function overriding isn't a thing anymore on @strict. It's a hacky weird dynamic behavior. If you want it, use lambdas.

Closing as I never guaranteed backwards compatibility with @strict (only for very widely used / common programming stuff)
