On: On leading underscores and names reserved by the C...

[SAI_Peregrinus]

The C is of course a pirate's favorite language. It might end up with "water" and "land" types in the standard some day. So `bool iswater()` and `bool island()` functions might be needed! You might need to check if the island structure you got is really land, so `island(&possible_island)` would obviously help and not cause any confusion to readers of the code.

Aye, any pirate's first love be the C

[sokoloff → SAI_Peregrinus]

You might want to know if you have a small piece of land surrounded by water, so we need

  isisland(x);

Or to know if an element is a member of a particular terror group (or an Egyptian goddess):

  isisis(y);

[cozzyd → sokoloff]

And if you want to know if some territory is claimed by a particular terror group (or Egyptian goddess, or post-metal band) there is the venerable

  isisisland(z);

In this case you'd typically then construct a memory fence.

[cozzyd → SAI_Peregrinus]

You just have to pass the pirate flag to your compiler

[0xADD1E → cozzyd]

I think you’ll find it’s actually called an arrgument

[Gibbon1 → SAI_Peregrinus]

Of course depending on how locale is set will effect the results of island() and iswater()
