You are right again. :) However, putting the lazy-taking function "outside" the whole expression makes it visible right away, making easy for me to realize that the execution order may be different from common chains.
"lazy" aka "named parameters" semantically works just like macros using textual substitution. Just imagine that it is inlined in situ and it becomes clear what is happening.
I believe it was the common parameter transfer mode in Algol, but programmers found it terribly confusing, so just about all languages that followed have avoided it. So if anyone gets confused, then find some comfort in knowing that people found it confusing 50 years ago too. :^)
