Examples of current syntax:

# following two are equivalent
my.prop1 = $script:javascript:inline{ 1 + 2 }$
my.prop2 = $script{ 1 + 2 }$
 
my.prop1 = $script:groovy:file{ /home/me/script.groovy }$
my.prop1 = $script:javascript:url{ file:///home/me/script.js }$

This is a bit cumbersome. We propose to relax the syntactic constraints and allow using 'S' or 's' instead of 'script', and only specifying the first character of each possible script source type ('u' or 'U' for url etc...)
