This is the map syntax:

value = string | number

simple = [<type>:]<value>

array = [<type>] '[' <value> [, value]* ']'

list = [<type>] '<' <value> [, value]* '>'

entry_value = simple | array | list | map

entry = <key>=<entry_value>

map = '{' <entry> [, entry]* '}'

Here is an example of a command and the result of its execution:

fw>$go {a=int:10,b=float:3.14,c=mystring,d=20}

    d = 20 (class java.lang.String)

    b = 3.14 (class java.lang.Float)

    c = mystring (class java.lang.String)

    a = 10 (class java.lang.Integer)

More examples:

    go { simple = b, array = int[10,30,30], list = <string1,string2>, map = {a=b, b=c} }

    go { 'my key' = 10, value = 'quoted value', escaped = 'contains the special \' character' }
