Motoko needs less parentheses (tweet)

[ggreif]

In many languages their grammar necessitates parentheses in many places to make them unambiguously parseable. In Motoko you can get away with much less. The rule of thumb is that if there is that single thing in parentheses, then the parentheses are probably redundant. E.g. #err e instead of #err(e), if tracked {...} instead of if (tracked) {...}. Same for switch d, case null, etc. You can even call functions in Bash-style: foo arg and define lambdas as func p = ... when the pattern is just a single token, though you have to consider whether your audience is okay with that!
