not exactly, {String[]} is parsed this way in SRFI 105 curly-infix:
> '{String[]}
'($bracket-apply$ String)

String[] without being in  { } is an error:

scheme@(guile-user)> 'String[]
$1 = String
While compiling expression:
Syntax error:
unknown location: unexpected syntax in form ()

and in Racket with a srfi-105 reader:
> 'String[]
'String
#%app: missing procedure expression;
 probably originally (), which is an illegal empty application in: (#%app)

but this works but is useless:
scheme@(guile-user)> '(String[])
$2 = (String ())

> '(String[]) ;;racket
'(String ())

i'm writing a converter from srfi-105 curly infix to scheme prefix , i
have a racket version in R5RS that should be portable to any scheme
and can convert any curly-infix  scheme code to prefix scheme but the
scheme should be R5RS compliant and i'm not sure Kawa is ?

this could be a solution, i suppose it evaluate the string as if it
was a kawa expression, but it is not very elegant if the [] are used
often in kawa code , but it is a solution indeed.
it works , the square bracket in a string is not modified by the reader:
scheme@(guile-user)> '(call-with-input-string "(String[])" read)
$3 = (call-with-input-string "(String[])" read)

i just adapted the curly-infix2prefix.scm for kawa, it is in attachment.
It convert a curly-infix program in prefix scheme allowing to use
syntax of SRFI-105 curly infix with Racket.But it is in command line
not integrated in REPL.
