Eric Wilhelm asked me to chime in here.
is_deeply() is about checking that two structures contain the same values.
This is different from checking that they're the same *things*, that they are
in fact the same object or reference.
You need both.
Reading eqv() it seems that yes, it is doing like

Actual
Well, the subject line already contains my question. I wrote some tests
about scalar autovivification. The short sequence:
my Str $x;
$x ~= 'a';
produces 'Stra' in pugs, because $x contains a Str proto object, that
stringifies to the type name.

Given that we have
say +'12';# 12
say +'0b1100';# 12
say +'0x0c'; # 12
what should the following produce?
say +':2<1a>';# 0? Failure? 12?

If you ask me, "best practices" evolve as a countering force to enough
people using less-than-ideal practices to cre

Recently, in November, we've had reason to clone the Rakudo Test.pm
and add an implementation (viklund++) of is_deeply, for testing
whether two arrays, pairs or hashes are deeply -- recursively --
equivalent. The method does what you'd think it does, checks the types
of its parameters and recurses
