David,
On the off-chance that you have not considered this, how about factoring
the long if-else chain into a function that uses early returns, like:
fn (...) -> .. {
if (f()) {
// ...
ret;
}
if (g()) {
// ...
ret;
}
if (h()) {
// ...
ret;
}
// ...
}
I don't think it is a syntactically pretty as what you propose, but it
does avoid adding a possibly rarely-used special case to the syntax.

Dear Rusties,
I am currently writing in C++ code that involves long strings of `if
... else if ... else if ... else if ...` and it dawns to me that we can
certainly sightly tweak the syntax of Rust to make such code much nicer.
Consider the following extract:
if (f()) {
// ...
} else if (g()) {
// ...
} else if (h()) {
// ...
} else {
// ...
}
