[Templates] Syntactical Scalar call

I was just putting in the code to handle it in Alloy (really not very bad at 
all - I hope TT3 will be easy to hack on too).

I just found another benefit that the .*method call can have - it is almost 
the same as .method, but it won't fall back and look for an hash key by that 
name if the object is a hashref based object.  So if .*method doesn't exist - 
then you get a die right then and there - rather than normal .method behavior 
which checks if obj->{method} exists.
