JW> Date: Fri, 21 Jul 2017 08:59:33 +0100 JW> From: Joseph Wright <[log in to unmask]> JW> In the latest CTAN update, \bool_if:n(TF) has been made *greedy*: JW> \bool_lazy_... functions are available for lazy evaluation. (The latter JW> have a different input syntax which does not suffer from the issue that JW> affects \bool_if:n(TF).) Any code which still assumes lazy evaluation JW> for \bool_if:n(TF) will therefore need adjustment. Would not it be a little gentler to the developers to keep \bool_if... lazy and introduce a new family \bool_greedy...? -- Good luck -Boris Because . doesn't match \n. [\0-\377] is the most efficient way to match everything currently. Maybe \e should match everything. And \E would of course match nothing. :-) -- Larry Wall in <[log in to unmask]>
