I.e. Inf compares equal to itself - is this intentional?


Yes, and we didn't invent this concept.


Heh. That's what you'd expect before reading IEEE.
After understanding all details of the IEEE standard, it's where you 
return (but only for infinities, not for NaNs) :-)


> This area is governed by IEEE 2008-753 standard, section 6.1 of which 
has this to say on infinities:


"The behavior of infinity in floating-point arithmetic is derived from the 
limiting cases of real arithmetic
with operands of arbitrarily large magnitude, when such a limit exists. 
Infinities shall be interpreted in
the affine sense, that is: −∞ < {every finite number} < +∞"


While that paragraph does not define how Inf relates to Inf, I see 
elsewhere that IEEE indeed defines Inf == Inf (and -Inf == -Inf).


I thought infinities were just a slightly tamed version of NaNs, but 
that was a misconception on my side.



It's not the only departure from mathematical result for the sake more 
practically useful results.


I know :-)

Good thing that we have === so we can compare at the representational level.

Are you sure that's the case? i definitely see SSL-related verbiage in

"switch-to-ssl()" and "starttls()" methods.

I was looking over at

Be nice is the basic Net::SMTP did support SSL and TLS too.

Same thing as when you asked about attaching files; I think I mentioned at
the time it also didn't include headers. Subject: is probably the most
important header --- although many mail systems will reject it if it also
doesn't have From: and preferably Date: and Message-Id:.

You might poke around to see if there is a module that implements at least
RFC822 and preferably RFC2422 to build a proper message.

here I would use explicit string concatenation to make it clearer you
are using two variables on the same line. Don't you miss a double
tick?

Yes, and we didn't invent this concept. This area is governed by IEEE 2008-753 
standard, section 6.1 of which has this to say on infinities:

It's not the only departure from mathematical result for the sake more 
practically useful results. Division by zero has well-defined behaviour in 
floating point math, and Rationals in Num view preserve it:

 m: say <1/0> == Inf
 rakudo-moar 320c2f: OUTPUT: «True␤»

Then I'd hate to tell you, but such a value exists in most languages: a NaN:

   else { AddToReport ( "Completed with $ErrorCount errors\n" ); }

   my $StringFullOfLineFeeds;

   my $client = Net::SMTP.new(:server("smtpout.secureserver.net"),
