    Affects Versions: 0.15.0

Currently the TOMAP function only supports a parameter list of values.
Triggered by reading http://stackoverflow.com/q/17847970/ 
{quote}I want to convert a bag of tuples to a map with specific value in each tuple as key. Basically I want to change:
\{(id1, value1),(id2, value2), ...\} into \[id1#value1, id2#value2\]{quote}

I propose to make the TOMAP accept both the current form
{code}TOMAP($0, $1, $2, $3){code}
and a new form where the a single parameter: 
A bag of Tuples where each Tuple has exactly two fields: a "key" and a "value".
