ans then thought it's a pity to open/closes the braces just
for a
simple statement. Would it be possible to have a template to
simplify this to:

if (comparison)
Break!(expression);

or even at the language level:
---
if (comparison)
break(expression);
if (comparison)
continue(expression);

so far it looks like it's only possible using a string mixin,
which is a quite unelegant solution (because for example you
loose the IDE completion while writting the statement):
---
auto Break(string statement)
{
return format("{%s;break;}", statement);
}
// unelegant but works...
if (condition)
mixin("myVar = 8".Break);
if (condition)
mixin(q{myVar = 8}.Break);
---
Any other solution ?
Take a look at lazy function arguments if you really want this.
Personally I think you'll end up saving a small handful of
keystrokes (if any) at the expense of clarity.
Wait no, actually you do need mixins, I wasn't thinking. Unless
you make the if statement a function call / template...
