Is there a programming language that supports chained notation a < b < c to be used instead of a < b and b < c in conditional statements?
Example:
- if ( 2 < x < 5 )
- if ( 2 < x && x < 5 )
First statementlooks better to me, it's easier to understand and the compiler could use transitivity property to warn about mistakes (e.g. 5 < x < 2 would give a warning).
