Lua-like no parentheses call

[giann]

In lua if a function call has only one argument and it's a string or a table, parentheses can be omitted like this:

callMe "John"
join { 1, 2, 3 }

We could imagine something similar for buzz on literals only (not a named variable, named object init or enum case which would make the grammar too ambiguous):

// string
callMe "John"
// list
join [1,2,3]
// map
sum { "one": 1, "two": 2, "three": 3 }
// anonymouse object
send .{ data = "some payload" }
// pattern
match $"[a-z]+"

This would make writing configuration files in buzz or any other declarative thing easy/elegant.

for list possible ambigue with get index syntax: arr[i]

for list possible ambigue with get index syntax: arr[i]

good point

for list possible ambigue with get index syntax: arr[i]

good point

also:
somemap{ foo: "bar" }
possible ambigue with
var instance = ObjectInit{ }

Yes i think the only non-ambiguous and useful one would be anonymous objects:

callMe .{ data = ... }
