How to make function call without bracket (, )

[rawhuul]

Hi, I am making a DSL where I want to call function without putting arguments in brackets, like foo 1, bar 1, foo bar 1,foo bar baz 1 which will de-sugar to foo(1), bar(1), foo(bar(1)), foo(bar(baz(1)))

That would be difficult if you need it to work for any function name. For fixed function names you can probably define a custom syntax.

Or use a custom prefix like #foo 1, $bar 1 etc.

I searched the documentation but it isn't mentioned there, How can I achieve this?

Check out the section on custom syntax in the Book.
