Thanks. So, I have to dereference the variable I assigned the typeglob to in order to turn it back into a typeglob? For instance,

$val = *x;
print "@{ *{ $val } }";

[download]

Based on the output here:

print $val;

--output:--
*main::x

[download]

...it's not obvious that $val needs dereferencing.

All three also work if $var = \*x;.

But I did $var = *x, which is not the same:

$what = *x;
print $what, "\n";

$what = \*x;
print $what, "\n";

*main::x
GLOB(0x10082ad88)

It seems like in the first case, I wouldn't have to dereference $what into a typeglob, where I would expect to do so in the second case.

Also, why can I do this:

$fh = *STDOUT;

print $fh 'hello', "\n";  

--output:--
hello

[download]

...and not this:

$STDOUT = 10;
$fh = *STDOUT;

print ($fh + 2);

--output:--
2
