Building a map from an array of tuple.

Dear all,
I am trying to build a immutable map from an array of tuple, however I can't find the right syntax.
Map companion object contains an apply method to build from a varargs list of tuples, but I get an error.
scala.collection.immutable.Map(result);
error: type mismatch;found   : Array[(Double, com.gottex.gottware.common.datamodels.finance.math.termstructure.InterestRate)] required: (Double, com.gottex.gottware.common.datamodels.finance.math.termstructure.InterestRate)scala.collection.immutable.Map(result);
Why ? :)

yourTuple2Collection.toMap

to call the vararg method, tell the compiler you want to apply an array as a vararg param by adding this weird smiley:
:_*

Map(Array((1,2)):_*)
