A Thought…

An American lawyer, doctor, and engineer are arrested in France and sentenced to be guillotined. The lawyer is placed in the device first, and the executioner releases the blade. It jams half way down! The lawyer says, “By the laws of your land, you must let me go!” The executioner sighs and says, “Oui, monsieur, get out of here!” Next up is the doctor, and again the blade jams. “By the laws of your land, you must release me!”, and he is let go. Last up is the engineer. Would you believe it? The guillotine’s blade jams again! The engineer twists his head around, studies the mechanism, and announces, “Ah, I see your problem!”

Things that would be useful to see in a language.

A common idiom is looping “forever” (well, practically you need to exit that loop at some time).

forever {  ...  }

instead of

while (true) {  ...  }

The idea is that the keyword forever stands out more obviously to the reader, making it clearer what’s going on. In a language like C, you could define a macro forever to be replaced by while (1). Either way, the compiler should be on the lookout for perpetual loops, and check that there is a path out of it (some sort of accessible break; somewhere). Not finding a way out should be a warning, not an error, as there is GUI code which loops forever.
