You can only interpolate ONE level of array or object indirection in a string.
WORKS:
"... $foo[x] ..."
"... $foo->x ..."
FAILS:
"... $foo[x][y] ..."
"... $foo->x->y ..." //almost for sure it fails, never tried...
You can use curly braces in side a string to evaluate something:
WORKS:
"... {$foo[x][y]} ..."
"... {$foo->x->y} ..."

I personally think this is possibly the ugliest wart of variable/string interpolation.
Not sure how/why it came about, but it makes zero sense, really...
