Passing on script generated arguments to erl

Hi all,

I've run into a problem when using erl with a bash script that 
generates the arguments I want to use in erlang.

If I type something like this at the bash prompt everything works fine:

	[dolly:~/southpaw] david% erl -- 'foo 1' 'foo 2'

	Erlang (BEAM) emulator version 5.3 [source]

	Eshell V5.3  (abort with ^G)
	1> init:get_plain_arguments().
	["foo 1","foo 2"]


If I try the script that automatically generates the arguments (just 
assume that the WORKLOAD var is generated by a script):

	[dolly:~/southpaw] david% WORKLOAD="'foo 1' 'foo 2'"
	[dolly:~/southpaw] david% echo $WORKLOAD
	'foo 1' 'foo 2'
	[dolly:~/southpaw] david% erl -- $WORKLOAD
	Erlang (BEAM) emulator version 5.3 [source]

	Eshell V5.3  (abort with ^G)
	1> init:get_plain_arguments().
	["'foo","1'","'foo","2'"]


Can anybody give me some advice on the matter, I'm currently leaning 
towards creating a temp file containing the arguments but the solution 
doesn't appeal to me.

cheers,

--david.
