"inline" (scoped) definitions?

Howdy, y'all!

Just wondering if there's a way to define a directive/variable "inline"?

e.g.

Rather than:

innerDef = { g2 g }
stuff = \notes
{
    a4 a a a
    \innerDef
    c4 c c c
    \innerDef
}

[Result: a4 a a a g2 g c4 c c c g2 g]

you might be able to do:

stuff = \notes
{
    a4 a a a
    innerDef = { g2 g }
    \innerDef
    c4 c c c
    \innerDef
}

[Result (n.b., the same as above) = a4 a a a g2 g c4 c c c g2 g]

or, better still, define it as (during) the first call:

stuff = \notes
{
    a4 a a a
    { g2 g } == innerDef
    c4 c c c
    \innerDef
}

[Result (n.b., the same as above) = a4 a a a g2 g c4 c c c g2 g]

The benefit, of course, would be that you would be able to keep similar 
definitions "inline" and "together" (e.g., notes in the \notes block, 
time switches in the \global block, etc.), and in a well-defined 
"scope", which could help reduce score complexity.

Any comments?
