The vector may consists of a single string with EOL and indentation characters embedded.

The get.exception option allows the user to disregard Python exceptions in cases where safe calls to avoid the overhead of checking for them.

python.exec( c( "def concat(a,b):", "\treturn a+b" ) )
python.call( "concat", a, b)
