Okay, then this should be added as a new feature request in bugzilla.

From bash.info:
The basic form of parameter expansion is ${PARAMETER}. The value of
PARAMETER is substituted. The braces are required when PARAMETER is a
positional parameter with more than one digit, or when PARAMETER is
followed by a character that is not to be interpreted as part of its
name.
So...
The following works:
x="foobar"
foo=${x}copy # foo is set to foobarcopy
bar=$xcopy # sets bar to empty string
and also the following:
foo=${11} # the 11th arg
bar=$11 # bar is set to the 1st arg followed by "1"
Basically, when I use ${var}, then I don't have to think about the form
of the variable or what follows it.
