You can just do
=20
table_name =3D "CUSTOMERS"
x =3D promise { table_name }
puts x
=3D> "CUSTOMERS"
=20
though you have to then make sure that you leave that table_name
variable alone.
=20
table_name =3D "CUSTOMERS"
x =3D promise { table_name }
table_name =3D "MONKEYS"
puts x
=3D> "MONKEYS"

	Hi,
	=20
	I have a feature request (along with a quick-hack solution).
	=20
	Please ignore if this is already done or sounds crazy. :-)
	=20
	Problem: All the promises I make, cannot have any arguments ! !
	=20
	So something like this is what I have in mind:
	=20
	x =3D promise("CUSTOMERS") { |table_name|
long_running_query(table_name)}
	=20
	Admitedly, in this one-liner it does not make much sense. But if
the block had many many lines of code and referred to the block variable
at multiple places, suddenly it would be mean more to me.
	=20
	I have attached my hackish solution without really thinking all
the way thru.
	Thanks,
	=20
