...essor). JSR 269 does not let you modify existing source code, but when you cast an Element to the underlying AST node, you can actually modify the AST (which is what project Lombok does).

size_t n = sizeof myArray / sizeof *myArray;
That, to me, reads a l...
Does PowerShell support constants?

For instance:
set-variable -name test -value ([int64]100) -option Constant
To check,
$test | gm
And you'll see that it is an Int64 (rather than Int32, which would be normal for the...
