Functional extensions

A Java experiment gone wrong.

I started this due to the recurring annoyance that is only being able to compose expressions with lambdas and method references when said lambdas and method references are at the start of the expression.

For example, the following are impossible (yes, I am aware that composing these particular methods is smelly):

(String::trim).andThen(String::toUpperCase);

(s -> s.trim()).andThen(s -> s.toUpperCase());

My initial idea for this repo was to use wrapping methods to get around it:

// Static imports used
wf(String::trim).andThen(String::toUpperCase);

wf(s -> s.trim()).andThen(s -> s.toUpperCase());

but, as it turns out, the code above does not compile because the compiler infers the types as being Object and then complains it cannot find the methods.
