Fix error in Safari with "use strict"

[leedorian]

When using in Safari, got error:

SyntaxError: Strict mode does not allow function declarations in a lexically nested statement.

This because the "callPrint" function is declared in try catch statement.

Thank you for taking the time and effort for this PR.
Do you think we could have it work while keeping the "use strict"; declaration?
What version of Safari are you on?

[leedorian]

I did some changes on "callPrint" function, make it work in Safari when keeping the "use strict", and committed the merge request, please check.

That sounds good.
The commit seems to be missing though, could you please check?

Thanks!

Went with @3kthor3adward's #64 as it's simpler.
Thanks anyways @leedorian
