Breaking Go memory safety by violating concurrency safety.
// tear.go
// A simple demonstration of breaking Go memory safety by violating concurrency
// safety. We alias a shared slice variable -- which is a multi-word variable --
// and then reads/write that shared variable in parallel between Goroutines.
// If "torn slice: ..." is printed, something VeryBad(tm) has occurred...

Breaking Go memory safety by violating concurrency safety (#2: interfaces).
// teariface.go
// A simple demonstration of breaking Go memory safety by violating concurrency

// the net result is the itable pointer and target object pointer end up

[ ] language-specific IDE. Your IDE will not succeed. Here is why it will not succeed.
You appear to believe that:
[ ] Syntax highlighting is what makes programming difficult
[ ] Garbage collection is free
[ ] Computers have infinite memory
[ ] Nobody really needs:
