Oh, goodness, deary me -- this sounded so familiar I just had to do some delving
and hey presto! I refer you

Ooh, skimming that, I see suggestions for prefixes and suffixes to
represent types of cast (or hint).
That fits nicely with my thoughts on making "strict cast" a first-class
citizen of the language, rather than isolating it to function
signatures, e.g.:
$foo = 'abc'; $foo = (int)$foo; // OK, evaluates to int(0)
$foo = 'abc'; $foo = (int!)$foo; // ERROR
$foo = '42'; $foo = (int!)$foo; // OK, evaluates to int(42)
