Bash Version: 4.4
Patch Level: 19
Release Status: release

Description:
        Bash rejects valid function definitions

Repeat-By:

$ func() true
bash: syntax error near unexpected token `true'

# Variant#2
$ func() { true }
> ^C

Both forms seem to be valid per [1] and are accepted by (at least)
ash, zsh and mksh

Worth noting that the Variant#2 can be made to work in bash with an addition
of a semicolon:

$ func() { true; }
