[erlang-questions] Construct parameter dynamically, sometimes illegal?

[Caspar Florian Ebeling]

I'm really a bit confused about cases when it is not possible to
pass parameters which were created dynamically. An example:
this does not work,

    {ok, File} = file:open("writebench.data.erl",
			   [write, binary, raw, {delayed_write, math:pow(2, 12), 1000}]

but this does,

    {ok, File} = file:open("writebench.data.erl",
			   [write, binary, raw, {delayed_write, 65536, 1000}]

Shouldn't that evaluate to exactly the same thing?
