Just stupid serial protocols to talk between devices. Often you have problems with picking commands and responses out of noise and or garbage. Think half duplex RS485. Protocols that use one token for delineating messages have poor error recovery/synchronization. I think pythons grammar is rather poor as a result. Other languages are far better. It's important because it effects tooling because tooling often has to deal with broken input.

Eh, I wouldn't assign that too much importance. Most C/C++ tooling practically gives up on a missing closing brace and almost never gives the right error message.

C and vastly more so C++ have a lot of other problems. C compilers can give the right error message 95% of the. But They have an excuse since they are older languages. Python was developed in an era when people knew better.

Java and C# are examples of well designed grammars. Tooling was a first class requirement for C# and it shows. Where python will never have great tooling.
