Is it true that there is no shortcut for obtaining a method handle for
some code fragment?
That is, there is no way to write something like this?
MethodHandle repeatIt = (String x) -> x + x;
Instead it's necessary to give the expression a name and put it into a
static method somewhere, and
don't use the class loader which was used to define the class to
look up the name?

Even a simple code like the one below, there is no scalar replacement
(OSR or not),
Float f = new Float(0);
for(int i=0; ilength; i++) {
f = new Float(f + 1.0f);
}
float result = f;
System.out.println(result);
Last time I looked at this,
* John Rose:
As I recall, Doug Lea noted at the 2010 JVM Language Summit that
tail calls would seem to allow work-stealing algorithms to be
implemented somewhat more cleanly or efficiently. (How's that for
tentative?) A worker thread goes from task to task in a data-driven
way, similar to
* Remi Forax:
I would be surprised if tail calls give more flexibility. Usually
it's the opposite, the mini-interpreter wins in terms of flexibility:

This trick can work with a lexer because usually you don't keep states
between each
and enumConstantDirectory seem good candidates (callers
cache the value anyway or do additional work while accessing the field).
