SV RTL support for local for loops

[lighteningfingers]

I am trying the following RTL (a simple memory equivalence with clockgating):

always_ff @(posedge clk_g or posedge rst)
if (rst) begin
for (int i=0;i<16;i++) mem[i] <= 'd0;
out <= 'd0;
end
else if (clk_en) begin
if (wr) mem[addr] <= din;
else if (rd) out <= mem[addr];
end

I get the following error:
SBY 8:48:18 [memory_equiv_async] nomem: memory_equiv_async.sv:77: ERROR: syntax error, unexpected TOK_INT, expecting TOK_ID or ATTR_BEGIN or '{'

Are SV local var "for loops" supported like in the context above, for shorthand async reset of arrays.
