function body parsing incomplete

[sunshineco]

POSIX states that a function body is a compound command. This means that, among others, the following are legal (and widely supported):

% foo() { echo hello; }
% foo
hello

% bar() ( echo hello )
% bar
hello

% xyzzy() if true; then echo wizard; else echo muggle; fi
% xyzzy
wizard

% frobnitz() for i in $(seq 3); do echo $i; done
% frobnitz
1
2
3

Some shells also accept a simple command (in addition to compound) as the body. For instance, in dash and zsh:

% baz() echo hello
% baz
hello

However, flash's Parser::parse_function_definition() is too restrictive and only accepts a function body if wrapped in curly braces.
