Alright, we're cursed, aren't we? Gone are dreams of grace and order,
now we must indulge in patch and scratch.

Anyway, maybe we can ask bash to pre-formalize the PKGBUILD a little
bit so be can parse it more confidently com, by using abination of
`set -x` and `typeset`. For example, consider the following
troublesome PKGBUILD:

foo=(a \
  b # )
  'c: )'
)

package_one() {
  foo=(d
  'e: 4 #1')
}

package_two() {
  foo+=(z)
}

We can append to the end of it:

typeset -f package_one package_two

And then if you execute it with: PS4='' bash -x ./PKGBUILD, the output
is formalized, with comments stripped too:

foo=(a b 'c: )')
typeset -f package_one package_two
package_one ()
{
    foo=(d 'e: 4 #1')
}
package_two ()
{
    foo+=(z)
}

What do you think?
