When I was starting learning F#, it was hard for me to read code without braces. I was very much accustomed to searching for braces to find where are the function names and where are the arguments. When I see x(y, z) I immediately know that x is a function and y and z are the arguments it is called with. When I see x y z It's hard for me to infer anything about the code.

There is some "golden point" between having too much and too less "punctuation symbols" in the code and it mostly depends on what the reader is accustomed to. This, sadly, slows down advancements in programming languages because people won't want to learn languages that are fundamentally different from what they know already.
