Initializing Arrays

[Joseph Bell]

Hi.

I'm new to D but not new to programming.  I had a few questions 
regarding  arrays and their initialization:

// celsius.init will be 100, the boiling point of water
typedef float celsius = 100.00;

If I declare an array of type celsius to group the low, average, and 
high temperature:

celsius[3] temps;

I'd like to be able to default the elements to something other than the 
value of celsius.init:  a syntax like

celsius[3] temps = [0, 20, 18];

In the global namespace (outside of main) the gdc compiler doesn't have 
any issues with this and gives me what I expect, temps[0] = 0.0, 
temps[1] = 20.0, and temps[2] = 18.0.  Within main however I get errors 
such as:

arrayex.d:22: Error: cannot implicitly convert expression ([0,20,18]) of 
type int[3] to celsius.

Is there a way to uniquely specify the default value of each element of 
an array in this manner in a non-global namespace?

Many thanks for any insight.

Joe
