Never been a problem for me, an ST user.
When I'm debugging, I'm mostly debugging templates - I use a simple
driver model, so not a lot of code to handle, but plenty of templates.
Sor example, this causes difficulty when I use template debugging mode
(outputting angle backets for example), since this causes my template
conditionals to not work properly (there's always some strings output -
the angle brackets and template names - so conditional is never empty);
I think what might be useful here is a way to separate those "template
debugging outputs" from my "usual expected" outputs. Perhaps stdout and
stderr, except you'd probably need a .sync/ .flush after each element is
output, so that the streams 'merge' properly, so that on the screen
(stdout + stderr), you the output which includes debugging output, but
in my output file and within the template processing proper (just
stdout) normal ST output would appear. All that disk/ stream syncing
would slow things down, but we're in debugging mode, so that's
