trait ResourceLoan extends AnyRef

A mix-in trait which provides Java's basic "try-with-resources" statement.

Usage example:

import net.java.truecommons3.shed.ResourceLoan_
val out: OutputStream = ...
loan(new PrintWriter(out)) to { w: PrintWriter => w.println("Hello world!") }

In this example, w.close() is guaranteed to get called even if the to-function terminates with a Throwable.

In general, if the to-function throws a throwable t1 and the AutoCloseable.close() method throws another throwable t2, then the throwable t2 gets added to the throwable t1 using t1.addSuppressed(t2).
