Re: 'Raw Expressions'


Thanks guys.  I'm too used to thinking of declaring variables and
strong types.  If I had an input that was constrained to have a head of
Integer (e.g. x_Integer), then Set[y, N[x]] would create a variable y
with a head of Real.

e.g.

f[x_Integer] := Module[{y = N[x]}, Print[Head[x]];Head[y]]
f[2]

I don't yet see the forest for the trees.

Matt
