Someone who needs this tutorial may also need help with concepts like scalar context and when it's implied.
Indeed. My intention was (and is) to link to a tutorial on context, at such time as one is available.
It's clear what's meant if the scalar context is made explicit like so:
$stuff = scalar @things;
Perhaps you missed where I wrote:
You can always force scalar context on an array by using the function named scalar:
print "# Elements: ", scalar(@array), "\n";
I should mention that the lack of comprehensive examples was intentional, and is why I included "Reference" in the title of the tutorial.
A word spoken in Mind will reach its own level, in the objective world, by its own weight
