Is this both legal and safe?:
foreach(key; assocArray)
if(key != "foobar")
assocArray.remove("foobar");
If not, then what about this?:
foreach(key; assocArray.byKey())
if(key != "foobar")

Hi,
I'm looking for a way to do call different functions within a
loop, so I won't have to write multiple functions with the same
looping mechanism.
I'm not sure if I'm explaing this very well, but this very simple
example should clarify:
void foo(int[] arr)
{
foreach(int val; arr)
As long as there is \" I get the same error.

This is what I have now (incorperated part of your suggestions):
http://codepad.org/wjaSgppT
It looks good. It's not a strongly typed code (because states are
just chars), and it's not much flexible because UTM is not
templated on Symbol and State, but for this task it's OK.
