Can't we write "use IPC::Run 0.98;" and let
some other code manage the version comparison?
We can, but that AFAIK (Andrew might have a better answer) requires the below
diff which I think leaves some readability to be desired:
- (eval { require IO::Pty; } && eval { $IPC::Run::VERSION >= '0.98' });
+ (eval { require IO::Pty; } && !!eval { IPC::Run->VERSION('0.98'); 1 });
Maybe I'm missing something, but I was envisioning
eval { require IO::Pty; use IPC::Run 0.98; }
with no need to do more than check if the eval traps an error.
You need to be careful with "use". It is executed in the compile phase, so I'd avoid it here.
