Re^3: How to identify incorrect subroutine calls in a perl program

Calls without parens need to go to pre declared subs, hence a compile time error.

 perl -c -we" use strict; Log 'There is an issue'"
String found where operator expected at -e line 1, near "Log 'There is
+ an issue'"
        (Do you need to predeclare Log?)

I fail to see how that's relevant. dragonchild said that importing would result in a compile-time error. That would only detect a typo in the previously-non-existent import. It wouldn't identify incorrect calls at compile-time. dragonchild didn't suggest omitting the parens. dragonchild even used parens in their post, just like the OP. Hence no compile-time errors would have resulted from their suggestion. Finally, omitting parens wouldn't even have worked well at the time of the post. For best results, `use v5.28;`/`no feature qw( indirect );`/`no indirect;` is required, but the post predates these.	[reply] [d/l] [select]
