Comment by rich...@zschech.net:
I had an idea how to reduce the code required for the immutable collections
mutation methods throwing `UnsupportedOperationException`:
If the compiler detects that the bodies of two methods are the same then it
can use the same Java Script method. For example in sudo Java / Java Script
code:
{{{
var throwUnsupportedOperationExceptionMethod = function() {
throw new UnsupportedOperationException?();
}
immutableCollection.add = throwUnsupportedOperationExceptionMethod;
immutableCollection.addAll = throwUnsupportedOperationExceptionMethod;
immutableCollection.clear = throwUnsupportedOperationExceptionMethod;
}}}
etc...
Java Script does not care if the number of parameters the caller is using
is different to what is defined. For example you can call with no issue: `
{{{
immutableCollection.add(e);
immutableCollection.clear();
}}}
This could be generalised to reduce the size of any code although it would
be time consuming to find methods with the same bodies.
