Escaping macros inside double quotes

Hi all. Is this supposed to work ?

#set($macroSignature = "\#myMacro()")

I can't make this work. I'm using velocity-1.3

Thanx. I'm already using that.
My problem is that I must include single quotes inside single quotes and
I can't scape them. The following example doesn't work :
'my \'example\'' 
Doesn't output my 'example'

I'd like to use double quotes because there are some variables and
macros the should be evaluated. Example :

<velocity>
#set ($macroName = '#myMacro()')
#set ($macroSinature = "\#render($macroName)"

$macroName
</velocity>

Should output

#render(#myMacro())

You should be able to just do

   #set($macroSignature = '#myMacro()')

The reason is that single quotes don't attempt to 'render' their 
content.  For example :


#set($foo = "I'm foo!")
#set($bar = '$foo')
#set($woogie = "$foo")

$foo
$bar
$woogie


will output :

I'm foo!
$foo
I'm foo!
