"B" and "C" are equivalent but "D" is somethig else.
"B" and "C" set the property named by the value of $myvar.
in "D" the variable-name is '$myvar' (not 'myvar').
if you set
$myvar = "foo";
${'$myvar'} = "bar";
then "B" and "C" will set $this->foo, but "D" will set $this->bar.
it's not that bogus.
