Poll: Fortran 202X Conditional Expressions syntax

[certik]

Btw, and if only variables are used (such as yours (predicate => then-var : else-var)), then that can be implemented already as ifthen, the implementation is here:

202X feature: Conditional Expressions

I was wondering whether we could already implement a function ifthen which allows the most basic handling of conditional expressions (like absent arguments). Here is an implementation I was able to come up with: module m_ifthen implicit none contains pure function ifthen(condition, tval, fval) result(val) logical, intent(in) :: condition real, intent(in), optional :: tval, fval real, allocatable :: val if (condition) then if (present(tval)) val = tval …
