This file creates and mounts a ramdisk on OS X (10.5+, I believe)

Handy for setting up test environments.  I use it for git like so:

device=`ramdisk 250 Git_Test`
export GIT_TEST_OPTS='--root=/Volumes/Git_Test'
make test
hdiutil detach $device

Migrating PAST to NQP and newPOST

Abstract

Benabik

In NQP, all variables get declared at the beginning of the block. This makes the following code fail:

my $old  := $*VAR;
my $*VAR := $new;

Instead of the old (outer) value of the contextual $*VAR, $old contains Undef. The following one line fix to nqp-rx seems to solve this problem by making NQP declare variables at the same point in the generated PIR as they are in the NQP code.
