nested `` quotation marks

is it possible to nest the `command` quotation marks.

for example
TEST=`echo `hello_world_program``
YES i know that program is completely pointless and can just as easily be done TEST=`hello_world_program` but that's not the point

Thanks in advance

You can escape them with \, or what I do is use $( ) instead for this exact reason. Escapes get pretty ugly after one layer of nesting.
