Another example is that Chill is a strongly typed + language, and certain expressions that violate the type constraints + may still be evaluated if gdb can do so in a meaningful manner, while + such expressions would be rejected by the compiler. The reason for + this more liberal behavior is the philosophy that the debugger + is intended to be a tool that is used by the programmer when things + go wrong, and as such, it should provide as few artificial barriers + to it's use as possible.
